∠A = 22.62 degrees
∠B = 67.38 degrees
The sum of ∠A and ∠B is 90°. ∠A and ∠B are complementary angles.
Step-by-step explanation:
∠A = 22.62 degrees
∠B = 67.38 degrees
The sum of ∠A and ∠B is 90°. ∠A and ∠B are complementary angles.
Which angles are complementary to each other?
2 right angles cannot complement each other2 obtuse angles cannot complement each other2 complementary angles are acute but vice versa is not possibleWhat is the formula for Complementary angles?
Complementary angles formulae. To find the complement on an angle, say ' x ', when expressed of radians, use the formula below: Complement of x rad = π/2 - x. For example, The complementary angle of 1/3π radian = π/2 - 1/3π = π/6 rad. To find the complement of an angle, say ' y 'when expressed in degrees, use the formula below: Complement of y ° = 90° - y .

Answer:
The volume of the metal is:
[tex]V_{t}=548\: cm^{3}[/tex]
Step-by-step explanation:
First, let's find the volume of the front face of the square:
[tex]V_{1}=12*7*1=84\: cm^{3}[/tex]
The back face is the same, so we have:
[tex]V_{2}=84\: cm^{3}[/tex]
The volume of the side faces will be:
[tex]V_{3}=7*10*1=70\: cm^{3}[/tex]
[tex]V_{4}=70\: cm^{3}[/tex]
And finally, the volume of the top and bottom side faces of the box will be:
[tex]V_{5}=12*10*1=120\: cm^{3}[/tex]
[tex]V_{6}=120\: cm^{3}[/tex]
The total volume of the metal will be:
[tex]V_{t}=V_{1}+V_{2}+V_{3}+V_{4}+V_{5}+V_{6}[/tex]
[tex]V_{t}=2(84)+2(70)+2(120)[/tex]

A rectangular swimming
pool has a perimeter of
150 meters. The length of
the pool is twice the width
of the pool. What is the
length of the pool?
Answer:
77
Step-by-step explanation:
perimeter=150
lets name the length x
length=x
width=x-2
2[x±x-2]=150
2x±2x-4=150
4x=154
154÷4=77
x=77
The length of the pool is 50 meters and this can be determined by using the formula of the perimeter.
Given :
A rectangular swimming pool has a perimeter of 150 meters. The length of the pool is twice the width of the pool.The following steps can be used in order to determine the length of the pool:
Step 1 - The formula of the perimeter of the rectangle is given by:
P = 2(l + w)
where l is the length of the rectangle and w is the width of the rectangle.
Step 2 - According to the given data, the length of the pool is twice the width of the pool that is:
l = 2w --- (1)
Step 3 - Now, substitute the known terms in the formula of the perimeter.
150 = 2(3w)
150 = 6w
w = 25 meters
Step 4 - Now, substitute the value of w in the equation (1).
l = 2(25)
l = 50 meters.

A quadratic function has a vertex of (0,7) and passes through the point (2, 3). Which of
the following is the equation of the graph of the quadratic function?
Answer:
Y = -2X + 7
Step-by-step explanation:
Y = a(x-h)^2 + k
From (h,k) h = 0 k = 7 x = 2 y = 3
3 = a(2-0) + 7
3 = 2a - 0 + 7
Collect like terms
2a = 3 - 7
2a = -4
Divide both sides by 2
2a/2 = -4/2
a = -2
y = a(x-h) + k
y = -2(x-0) + 7
y = -2x + 0 + 7
y = -2x + 7 or
y + 2x - 7 = 0
The longest side of triangle is 10 cm which group of line segments could form the other 2 sides of the triangle
Answer
A 5cm and 5 cm
B 7cm and 8cm
C 4cm and 4cm
D 9cm and 10 cm
Please i need to know
Answer:
The group of line segments that could form the other 2 sides of the triangle is;
B. 7 cm and 8 cm
Step-by-step explanation:
The triangle inequality theorem states that the sum of the length of any two sides of a triangle is larger than the length of the third side
The given parameter of the triangle is that the length of the longest side of the triangle = 10 cm
Let, 'a', and 'b', represent the remaining two sides of the triangle
Therefore, by the triangle inequality theorem, we have;
(1) a + b > 10 cm
(2) 10 cm + a > b
(3) 10 cm + b > a
The option that satisfies condition (1), (2), and (3) are options 'B' and 'D', for which we have;
7 cm + 8 cm = 15 cm > 10 cm
10 cm + 7 cm = 17 cm > 8 cm
10 cm + 8 cm = 18 cm > 7 cm
9 cm + 10 cm = 19 cm > 10 cm
10 cm + 9 cm = 19 cm > 10 cm
10 cm + 10 cm = 20 cm > 9 cm
Therefore, the possible combination of the other two sides are;
7 cm and 8 cm or 9 cm and 10 cm
However, a side of option 'D' is 10 cm and given that the longest side of the triangle = 10 cm, the length of each of the other two side should be less than 10 cm and the only given possible combination of the other two side should be option 'B', 7 cm and 8 cm.
Answer:
B 7cm and 8cm

Explanation:
In this answer choice, we effectively have two columns. In the first column is simply R and B, with R over B. This represents spinning either red (R) or blue (B).
Depending on the outcome, you branch the same outcomes from that.
So if you spin R, then you'll have R and B branch off that. Same idea applies to blue as well.
Something like choice D doesn't work because we have R show up twice at the very bottom.

That is a question about spatial geometry.
In our problem, we have to calculate lateral surface area of a triangular prism. Let's see how to solve this.
A triangular prism has 5 faces: 3 equals rectangles and 2 equals triangles. If we can find a way to calculate those areas, we can solve the problem.
The first thing that we should note is that we know the dimensions of the rectangular faces. The dimesions of the rectangular are 5cm and 8cm. To calculate the are of a rectangle, we multiplicate the dimensios of it. Therefore, each rectangle (in our problem) has [tex]5 \times 8 = 40cm^2[/tex] of area. There are 3 rectangles, so, the sum of the 3 rectangular area is [tex]40 + 40 + 40 = 120cm^2[/tex].
Now, we need to know the area of the triangular areas. To calculate the area of a triangle, we need to know the value of the base and the value of the height.
In the image, we know the value of the base, but we do not know the value of the height. To calculate the height, we can use the Pythagorean Theorem because we have a right triangle. (Please find attached the document.)
The Pythagorean theorem says that:
[tex]\boxed{a^2 = b^2 + c^2}[/tex]
a is the hypotenuse and b and c are cathetus.
In this right triangle, the value of the hypotenuse is 5cm and the value of one cathetus is the half of 6cm (that is 3cm). Let's replace the values in the expression:
[tex]a^2=b^2+c^2\\5^2= 3^2 +c^2\\25 = 9 + c^2\\c^2 = 25 - 9\\c^2 = 16\\c = \sqrt{16} \\c = 4cm[/tex]
Now, we know the bases and the height of the triangular areas. To calculate the area of a triangle, we multiply the base and the height and we divided the result by 2. See the expression:
[tex]\boxed{A_t=\frac{b\times h} {2}}[/tex]
b is the base and h is the height. Let's replace the values in the expression:
[tex]A_t = \frac{b\times h}{2} \\A_t = \frac{6\times4}{2} \\A_t = \frac{24}{2} \\A_t = 12cm^2[/tex]
So, each triangular area has 12cm² of area. Therefore, the sum of the triangular areas is [tex]12 + 12 = 24cm^2[/tex].
Finally, we know that the sum of the rectangular area is 120cm², and the sum of the triangular area is 24cm², so, the lateral surface area is [tex]120 + 24 = 144cm^2[/tex].
In other words, they didn't choose the correct answer because the correct answer is J) 144 cm².
I hope I've helped. :D
