Answer/Step-by-step explanation:
Given:
C = right angle = 90°
BC = a = ?
AB = c = 12
AC = b = 9
Required:
a, <A, and <B
Solution:
✔️Find a using Pythagorean Theorem:
a = √(c² - b²)
a = √12² - 9²) = √63
a = 7.93725393 = 8 (nearest whole number)
✔️Find A by applying trigonometric ratio:
Thus,
Reference angle = A
Hypotenuse = 12
Adjacent = 9
Therefore,
[tex] cos(A) = \frac{adj}{hyp} = \frac{9}{12} [/tex]
[tex] cos(A) = 0.75 [/tex]
[tex] A = cos^{-1}(0.75) [/tex]
m<A = 41° (nearest whole number)
✔️Find B:
m<B = 180 - (90 + 41) (sum of interior angles of triangle)
m<B = 49°

Which table of values represents the equation y = 1/2x?
Answers
Answer:
The third option choice
Step-by-step explanation:
In the equation all your doing is halfing the x to get y
Or multiplying it by . 5
So half of what your x is is what your y is
An equation is formed of two equal expressions. The table that represents the equation y=(1/2)x is the third table.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The table that represents the equation y=(1/2)x can be seen as,
x = 1
y = (1/2)×1 = 1/2
x = 4
y = (1/2)×4 = 2
x = 5
y = (1/2)×5 = 5 1/2
x = 8
y = (1/2)×8 = 4
The table that represents the equation y=(1/2)x is the third table.

12 1/2 - 9 1/4= What is the answer to this question?
Answers
Answer:
3 1/4
Step-by-step explanation:
First you would convert them to improper fractions with common denominators.
12 1/2 >>>> 25/2
9 1/4 >>>>>> 37/4
to get a common denominator, you would multiply 25/2 by 1/2 to get 50/4.
50 - 37 = 13
so your answer would be 13/4

Because PEMDAS,
so first deal with exponents and 3 to the fourth power is 81. 6 to the fourth power is 1,296.
Next in PEMDAS is multiplication and division, so 1,296 times 81 is 104,976. Then 4 divided by 2 is 2.
Finally comes subtraction, 104,976 minus 2 = 104,974
how to find it is related to the opposite angle in a cyclic quadrilateral is equal to 180 degeres
Answers
Answer: The measure of ∠BEF=110°.
Step-by-step explanation:
Given: In cyclic quadrilateral ABCD, ∠C = 110°
Then, ∠A+∠C=180° [The sum of opposite angles in a cyclic quadrilateral is 180 degrees.]
⇒ ∠A+ 110°=180°
⇒ ∠A = 180° - 110°
⇒ ∠A = 70°
In cyclic quadrilateral ABEF,
∠A+∠E=180° [The sum of opposite angles in a cyclic quadrilateral is 180 degrees.]
⇒ 70° + ∠E=180°
⇒∠E=110°
Hence, the measure of ∠BEF=110°.

Step-by-step explanation:
For each part, write the equation that represents the line in slope-intercept form (y = mx + b) and standard form (ax + by = c where a, b, and c are integers and a is not negative).
Answers
Answer:
Graph
[tex]y = -x+1[/tex] --- Slope intercept form
[tex]y +x= 1[/tex] --- Standard form
Points
[tex]y = 2x-2[/tex] --- Slope intercept form
[tex]y -2x=-2[/tex] --- Standard form
Step-by-step explanation:
Solving (a): The graph.
From the graph, we have:
[tex](x_1,y_1) = (1,0)[/tex]
[tex](x_2,y_2) = (0,1)[/tex]
First, calculate the slope
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
This gives:
[tex]m = \frac{1 - 0}{0 - 1}[/tex]
[tex]m = \frac{1 }{- 1}[/tex]
[tex]m = -1[/tex]
The slope intercept equation is:
[tex]y = m(x-x_1)+y_1[/tex]
So, we have:
[tex]y = -1(x-1)+0[/tex]
[tex]y = -1(x-1)[/tex]
[tex]y = -x+1[/tex]
In standard form:
[tex]y = -x+1[/tex]
Add x to both sides
[tex]y +x= x-x+1[/tex]
[tex]y +x= 1[/tex]
Solving (b): The points
From the graph, we have:
[tex](x_1,y_1) = (0,-2)[/tex]
[tex](x_2,y_2) = (3,4)[/tex]
First, calculate the slope
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
This gives:
[tex]m = \frac{4 - (-2)}{3 - 0}[/tex]
[tex]m = \frac{6}{3}[/tex]
[tex]m=2[/tex]
The slope intercept equation is:
[tex]y = m(x-x_1)+y_1[/tex]
So, we have:
[tex]y = 2(x-0)-2[/tex]
[tex]y = 2(x)-2[/tex]
[tex]y = 2x-2[/tex]
In standard form:
[tex]y = 2x-2[/tex]
Subtract 2x from both sides
[tex]y -2x= 2x-2x-2[/tex]
[tex]y -2x=-2[/tex]

If you rewrote these percents as fractions which one could be written as a whole number over 10? A. 1% B. 5% C.25% D. 40%
Answers
Answer:
D. 40%
Step-by-step explanation:
Hi! All you basically need to do in this question is to really think. The tenths placement is what you are looking for.
Let us use money for example. a penny would represent 1%. It needs to be in tenths, 1/10, 2/10, 3/10, and so on to be a whole number. A penny is simplified to be only 1/100. This will not work.
B is 5%. This would represent a nickel. A nickel is simplified to be 1/20. This will not work. C is 25%. This would represent a quarter.
A quarter simplified is 2.5/10... not a whole number.
However 40% is 4/10, making it our answer.
Hope this helps!

Answer:
Y = theta = 32.68
Step-by-step explanation:
Formula
y^2 = x^2 + z^2 - 2*x*z * cos(theta)
Givens
y = 55
theta = ?
z = 50
x = 90
Solution
55^2 = 90^2 + 50^2 - 2*90*50 cos(theta)
3025 = 8100 + 2500 - 9000 cos(theta) Combine the right
3025 = 10600 - 9000 Cos(theta) Subtract 10600
3025 - 10600 = -9000 Cos(theta)
-7575 = - 9000 Cos(theta) Divide by - 9000
-7575/-9000 = cos(theta)
0.8417 = cos(theta)
cos-1(0.8417) = theta
theta = 32.68
