Question

the measures of three angles of a triangle are given by (8x-10), (2x), and (3x-5). What is the measure of the larges tangle

Answer 1

9514 1404 393

Answer:

110°

Explanation:

The sum of angles of a triangle is 180°.

(8x -10) +(2x) +(3x -5) = 180

13x -15 = 180

13x = 195

x = 15

The largest angle is ...

8x -10 = 8(15) -10 = 110 . . . . degrees
