Question

can someone help me please I only got two things down :(

Answer 1

Answer:

60 is b and a is 50 because 70+60+50 going to equal 180 which is the degrees the line under it equal to.

Answer 2

Answer:

a= 60 degrees

b = 50 degrees

Step-by-step explanation:

Angle a is 60 degrees because the angle of a straight line is always 180 so if you do 180-120 you get 60 (the remaining angle of the straight line)

The three angles of a triangle also always add up to 180.

so if you add 70 + 60 you only get 130 and 180 - 130 equals 50
