Answer:

∠ 8 = 140°

Step-by-step explanation:

∠ 8 and 40° are adjacent angles and supplementary ( sum to 180° ), then

∠ 8 = 180° - 40° = 140°

Answer:

m∠8 = 140°

Step-by-step explanation:

40 and angle 8 are supplementary angles

this means they add up to 180°

so, you can make the following equation:

40 + m∠8 = 180

<em>subtract 40 from both sides of the equation</em>

40 - 40 m∠8 = 180 - 40

m∠8 = 180 - 40

m∠8 = 140

Hi can you please help me​
astra-53 [7]

Answer:

<h2>Area = 90 cm²</h2><h2>Perimeter = 53 cm</h2>

Step-by-step explanation:

area and perimeter of the given diagram

<u>area = 1/2 * base * height</u>

where base = 15 cm

        height = 12 cm

plugin values into the formula

area = 1/2 * 15 * 12

area = 90 cm²

<u>Perimeter = add up all sides (AB + AC + BC)</u>

where side BC = √(5² + 12²)

                   BC = 13 cm

Perimeter = 25cm + 15 cm + 13 cm

Perimeter = 53 cm

Given a sphere with a diameter of 6 cm, find its volume to the nearest whole<br> number.
mezya [45]

Answer:

Volume of the sphere is 1.13\times 10^{-4}m^3

Step-by-step explanation:

It is given diameter of the sphere d = 6 cm = 0.06 m

Radius of the sphere

r=\frac{d}{2}=\frac{0.06}{2}=0.03m

We know that volume of the sphere is given by

V=\frac{4}{3}\pi r^3

Therefore ,

V=\frac{4}{3}\times 3.14\times  0.03^3

=1.13\times 10^{-4}m^3

Therefore volume of the sphere is 1.13\times 10^{-4}m^3
