Question

One of the angles of a certain triangle is three times the second angle and the third angle is 16∘ smaller than the first. Find the three angles. *​

Answer 1

Step-by-step explanation:

$16 + a + a = 180 \\ 2a = 180 - 16 \\ 2a = 174 \\ a = \frac{174}{2} \\ a = 87 \\ \\ a = 87 \\ b = 87 \times 2 = 174$
