D) 65​

Answer 1

d). 65

please mark me as brilliant

Answer 2

Answer:

Solution:

We know that, sum of two supplementary angles = 180°

(3x + 15)°+(2x + 5)°= 180°

3x + 15 + 2x + 5 = 180°

> 5x° + 20° = 180°

> 5x = 180° - 20°

> 5x = 160°

x =\frac{160}{5}

5

160

> x = 32°

Step-by-step explanation:

32⁰ is correct answer
