Answer:

65°

Step-by-step explanation:

2x + 15° = 145° ( being vertically opposite angles)

2x = 145° - 15°

2x = 130°

x = 65°

Hope it will help :)✔

The value of x is 65 degrees.

When two lines intersect each other, then the opposite angles, formed due to intersection are called vertical angles or vertically opposite angles.

Given:

angles are: 145 and (2x +15)

As, the pair of angle are in relation of vertically opposite angle

145 = 2x +15

2x= 130

x= 130/2

x= 65 degree.

Answer:

m<1=117

m<2=99

Step-by-step explanation:

Answer:

Angle 1 is 117 degrees.

Angle 2 is 59 degrees.

Step-by-step explanation:

Let angle 1 be x, and angle 2 be y.

By the exterior angle theorem, x + 21 = 138, so x = 138 - 21 = 117.

Again, by the exterior angle theorem, 79 + y = x = 138, so y = 138 - 79 = 59.

Answer:

[tex]A=190.75\ cm^2[/tex]

Step-by-step explanation:

The diameter of a hemisphere, d = 9 cm

Radius, r = 4.5 cm

We need to find the surface area of the paperweight. The formula for the surface area of a hemisphere is given by :

[tex]A=3\pi r^2\\\\A=3\times 3.14\times (4.5)^2\\\\A=190.75\ cm^2[/tex]

So, the surface area of the paperweight is [tex]190.75\ cm^2[/tex].

Step-by-step explanation:

Let's simplify step-by-step.

−5y2−9y−4−(−2y2−y+8)

Distribute the Negative Sign:

=−5y2−9y−4+−1(−2y2−y+8)

=−5y2+−9y+−4+−1(−2y2)+−1(−y)+(−1)(8)

=−5y2+−9y+−4+2y2+y+−8

Combine Like Terms:

=−5y2+−9y+−4+2y2+y+−8

=(−5y2+2y2)+(−9y+y)+(−4+−8)

Answer: 1  13/25

Step 1: Write down the percent divided by 100 like this:

152% = 152/100

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As 152 is an integer, we don't have numbers after the decimal point. So, we just go to step 3.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(152,100) = 4. So,

(152÷4)/(100÷4) = 38/25 when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 152/100 is also equal to 1 13/25 when expressed as a mixed number.

Answer:

x=-7

Step-by-step explanation:

Answer:

x=7

Step-by-step explanation:

Simplifying

-1(8 + -3x) = 13

(8 * -1 + -3x * -1) = 13

(-8 + 3x) = 13

Solving

-8 + 3x = 13

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '8' to each side of the equation.

-8 + 8 + 3x = 13 + 8

Combine like terms: -8 + 8 = 0

0 + 3x = 13 + 8

3x = 13 + 8

Combine like terms: 13 + 8 = 21

3x = 21

Divide each side by '3'.

x = 7

Answer:

162 square feet

Step-by-step explanation:

Let the side lengths of the square be l feet each.

Then the diagonal together with any two sides forms an isosceles right triangle.

We can apply the Pythagoras Theorem, which says that, the sum of the squares of the two shorter legs equals the square of the hypotenuse ( the diagonal) in this case.

Divide both sides by

The area of the square garden will be 162 square feet.

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the square in a two-dimensional plane is called the area of the square.

Given that the length of the diagonal of the square is 18 feet. The area of the square will be calculated as,

Area = 1 / 2 x d₁ x d₂

Area = 1 / 2 x 18 x 18

Area = 9 x 18
