Question

hey pretty souls ❤️ plz answer (vertically opposite angles),solve the ticked questions(i.e. no.c and f)
plz solve in copy and send,it will be easy.have a good day.​

Answer 1

c). 2a+50=a. (vertically opposite angle are equal)

so, a= 50

now 2×50-50=50

100-50=50

50=50

so

now b+(2a+50)=180

b = 180-50

b=130

so c=130 ( vertically opposite angle are equal)

f) d=60 interior alternative angles

3b=180-60 in a line

3b=120.

and 4c = also 120. also in line

2a =60 vertically opposite angles

f=120. in a line

2a=60. already found

e =120 in line

Answer 2

Answer:

We know that if two lines intersect each other it always make (360°) angle

(a) given angle is 65°

so left angle = 1 a + 1 b + 1 c

= 3 abc

so equation = 65° + 3abc = 360°

3 abc = 360 ° - 65° = 295°

abc = 295° ÷ 3 = 98.99°................
