Find the angle measures. Justify your responses.
Given a||b, m∠1 = 71 degrees
Find: m∠5, m∠8

<5=71°

<8=109°

Step-by-step explanation:

m<5=m<1=71°

<1 and <5 are corresponding angles so they have the same angle measurement.

m<5+m<8=180°

180°-71°=m<8

m<8=109°

<5 and <8 are supplementary angles

hopefully this helps :)

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
