Answer 1

Answer:

hi mate

here is your answer. .

hope it will help. . .

thus

4x=40

5x=50

y =50+40 = 90

Answer 2

Answer:

let the ratio be x.

Step-by-step explanation:

4x+5x=third angle (given)

therefore,

9x+4x+5x=180(ASPT)

18x*=180*

x=180*/18=10*

4x=4×10=40*

5x=5×10=50*

9x=9×10=90*

hope you understand.
