Answer:
a = 9√2 and b = 9
Step-by-step explanation:
→ To find a, use the CAH triangle
9 ÷ cos (45) = 9√2
→ To find b, use the TOA
Tan (45) × 9 = 9
Solution given:
b=9 base side of isosceles triangle
a=
0
0(4)-4(0) = 0
16.1
B
Angle 4 × Angle 3 = 90
Complementary angles
11x + 4x = 90
15x = 90
x = 6
Angle 3 = 4x = 4(6) = 24°
9
