The measure of angle A is 60 more than twice its supplement. Find the measure of angle A *
A.86
B. 100
C. 120
D. 140

Hi there! :)

m∠A = D. 140°

Let the supplement of angle A be called "Angle B". Assign this angle a value of "x":

Write an equation to represent the value of Angle A: 60 + 2x

Supplementary angles sum up to 180°, therefore:

180 = x + 60 + 2x

Combine like terms and simplify:

180 = 3x + 60

180 - 60 = 3x

120 = 3x

120/3 = 3x/3

x = 40°.

Find the measure of Angle A by substituting this value into the equation:

2(40) + 60 = 140° = m∠A

answer: are you

step-by-step explanation:

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 !
