Answer:
x = -1/2
Step-by-step explanation:
-10x = 5
Divide both sides by -10.
x = -1/2
Answer:
a =
, b = - 2
Step-by-step explanation:
Given the 2 equations
9 = ab² → (1)
- 72 = a
→ (2)
Divide (2) by (1)
= 
- 8 = b³ ( take the cube root of both sides )
= b , that is
b = - 2
Substitute b = - 2 into (1) and solve for a
9 = a(- 2)² = 4a ( divide both sides by 4 )
= a
Answer:
Angle 3 = 180 - 45 - 113 = 22 degrees
Angle 1 = 113 degrees
Angle 2 = 180 - 113 - 22 = 45 degrees
