Answer:
103 degrees
Step-by-step explanation:
The sum of the measures of all triangles is 180 degrees. The two angles given total 77 degrees. Subtracting 77 from 180 leaves 103 degrees for the 3rd angle
it is the ans of midpoint PQ
Multiply both sides by d.
dm=a+64d
Flip the equation.
a+64d=dm
Add -64d to both sides.
a=dm−64d
<u>a=dm−64d</u>
