Question

12. Find the measure of the largest angle in the triangle shown.

Answer 1

Explanation:

all angles of a triangle sum to 180

180 = 15x + 24x +21x

180=60x

solve for x

then substitute that for 24(x) to get the angle

Answer 2

Hello! answer: 72

Explanation:

the largest angle is 24 × 3 = 72 because 21 × 3 = 63 is less and 15 × 3 = 45 is less and x = 3
