Question

AABC has the following measurements:

ZABC = 3x - 13
ZBAC = x + 16
ZACB= x + 2
How big is ZACB?
Angle ACB is
degrees.

Answer 1

38°

Explanation:

The sum of interior angles in a triangle is equal to 180°.

• To find the measure of angle ACB, we first need to find the value of x.

3x - 13 + x + 16 + x + 2 = 180

• Add like terms.

5x + 5 = 180

• Subtract 5 from both sides.

5x = 180

• Divide both sides with 5.

x = 36

Replace x with 36 in the given expression:

∠ACB = 38°
