Find The Value Of A And B A B class=

Sagot :

Answer:

a = 60

b = 60

Step-by-step explanation:

Vertical angles are congruent to each other

Vertical angle pairs:

AXE = YXC = 30

a = b

BXA = DXC + 90

Line AC is 180 degrees because of definition of a straight line.

This means AXE + b + DXC = 180 (Parts Whole Postulate)

Substitute given angle measurements

30 + b + 90 = 180

b = 180 - 12

b= 60

Since b=a, that means a = 60

Hope this helps :)

Have an awesome day!

Answer:

a = 60 degrees, b = 60 degrees

Step-by-step explanation:

30 + b would be a complementary angle which is 90 degrees.

30 + b = 90

b = 60

a would also be 60 degrees because they are vertical angles.
