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
A = 1
b = -1
a + b =
1 + (-1) =
1 - 1 =
0....so a + b = 0
additive inverse property states that every real number added to its additive inverse (or opposite) will equal zero.
