Question

PLEASE MAY I KNOW THE ANSWER. IT VERY URGENT ​

Answer 1

Answer:

sum of all angle =180°

so,

x+2x+5+3x-5=180

Step-by-step explanation:

x+2x+3x+5-5=180

3x+3x+0=180

6x=180

x=180/6

x=30°

Answer is option

D) 30°

Answer 2

Answer:

(C) 85 degree

Step-by-step explanation:

Let angle A=x degree , angleB = 2x+5 degree , angleC=3x-5degree

Therefore , x+2x+5+3x-5=180 degree

=) 6x=180

=) x=180/6=30

so, angle A=x degree = 30 degree

angle B=2x+5 degree = 2×30+5 degree = 65 degree

angle C=3x-5 degree = 3×30-5 degree =85 degree

Hence, the lergest angle is angle C i.e. 85 degree

HOPE IT HELPS!
