Answer:
x = 21
Step-by-step explanation:
Givens:
Every triangle's interior angles add up to 180°
The triangle has a right angle.
The triangle is isosceles (two equal sides and two equal angles)
Let's make an equation with the information we have already.
2 × (2x + 3) + 90 = 180
4x + 6 + 90         = 180
4x + 96                = 180
4x                         = 84
x                           = 21

Answer: a = 110ᴼ
Step-by-step explanation:
The angles on each line of the figure add to equal 180ᴼ
180 - 70 = 110
a = 110ᴼ
b and 70ᴼ are vertical angles, so their measures are congruent.
b = 70ᴼ
180 - 70 = 110
c = 110ᴼ
