Answer:
70
Step-by-step explanation:
we have the angle of vertex in the isosceles triangle = 180-2*bottom coner= 180-65/2=50
3 angles in the equilateral triangle are equal to 60
we have 50 + 60 +h =the angle of PQR =180
h=70
Answer:
18
Step-by-step explanation:
90-80=10
10*2=20
20-2=18
Coordinates: (3, -3)
this point R would be the same distance that point P is from point Q, fulfilling the statement of it being an isosceles triangle
