Answer 1

Answer:

55

Step-by-step explanation:

65 +60 = 125

180-125 = 55

X=55

Answer 2

Answer:

1. x=65°

2.y=40°

Step-by-step explanation:

1.

Here, total angle of triangle is 180°

therefore, A+B+C = 180°

so here given,

A=x ; B=65° ; C=60°

x+ 65+60= 180

x+ 125= 180

x= 180 - 125

x= 65°

2.

Here,

given A= y; B= 80° C=?

straight angle = 180°

therefore, C = 180 -120 = 60°

so here, we got angle B and C

now A+B+C = 180°

therefore y+80+60 = 180°

y+140= 180

y= 180-140

y= 40°

I hope it will help you...!!!
