Answer:
a)(x + 3) + (2x - 3) = 90
b)(x + 3) + (2x - 3) = 90
-3 -3
-------------------------------
x + (2x-3) = 87
+3 +3
------------------------------
x + 2x = 90
Simpify: x + 2x = 3x
3x/3 = 3
90/3 = 30
x = 30º
c)(30 + 3) = 33º for angle A
(2x30-3)= 57º for angle B
Step-by-step explanation:
Set them equal to 90º because complementary means 2 angles that = 90º
