Answer:

75°

Step-by-step explanation:

There are 180° in a triangle, so using the ratios and the 180° setup an equation. Solve for x.

5x + 9x + 10x = 180

24x = 180

24x/24 = 180/24

x = 7.5

To find the largest angle measure, use 10x since 10 is bigger than 5 and 9.

10x

10(7.5)

75°

Answer question 13 PLSSSSSSS

san4es73 [151]

Step-by-step explanation:

By Exterior Angle Theorem,

(x + 40)° + (4x - 5)° = (6x + 20)°

Therefore 5x + 35 = 6x + 20 and x = 15.

Hence angle QPT = (6 * 15 + 20)° = 110°.
