Question

Drag each label to the correct location on the figure. Not all labels will be used. Find the missing angle measurements. 60° 64° 45° 49° 53° 56° 64° 719

Answer 1

we know that

In any triangle the sum of the interior angles must be equal to 180 degrees

so

In the first triangle (bottom) we have

64+71+x=180

Solve for x

x is the missing angle

135+x=180

x=180-135

x=45 degrees

The first missing angle is 45 degrees

step 2

triangle of the top

we know that

The first missing angle is 64 degrees by vertical angles

so

we have that

64+56+y=180

solve for y

120+y=180

y=180-120

y=60 degrees
