Question

Hey mates! 50 pts!!

Please give the the right solution for the above 4 questions.

Need step-by-step answers. ​

Answer 1

Answer:

1st

90+2x = 180

2x= 90

x=45 (angle ADC)

so 45+100+y=180

145+y= 180

y= 35

2nd

(999+0.98)×99= 98999

4th

50° angle and angle opposite to y are alternative angle so they are same....

angle y is vertically opposite to it so y is 50°

now 50+50+x= 180

100+x=180

x= 80

hope it helps you
