What is m∠abc? the measure of angle abc = 60 degrees the measure of angle abc = 15 degrees the measure of angle abc = 45 degrees the measure of angle abc =75 degrees.

The measure of angle ABC is 60 degrees

Step-by-step explanation:

Let

x -----> the measure of angle ABC

we know that

The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles

so

In this problem

Solve for x

Subtract 75 both sides

therefore

The measure of angle ABC is 60°

1. V≈1244.07

2. V≈54286.72

3.V≈23816.41

4. V≈254.47

5. V≈4247.43

6. V≈21714.69

7. V≈4712.39

Step-by-step explanation:

use the formula V=πr^2h
