Question

Find the measure of angle ABC. A. 124 B. 97 C. 56 D. 51

Answer 1

180-32+15+5 = 3x

168/3 = x

X= 56 and now substitute 56 for x and u get ur angles 51 and 97

Answer 2

Answer D. 51

Step-by-step explanation:

Sum of the interior angles of a triangle is up to 180

.: 32+(2x-15) + (x-5) = 180

Group like terms

2x+x =180 - 32 + 15 + 5

When - and + sign cross equal sign it turns to the opposite

3x = 168

x= 168/3

.: X =56

Now put x = 56 in (x - 5)

Angle ABC = 51
