Solve for b, show your work

b= 47

Step-by-step explanation:

180-90 =90

90 -43 =47

b = 47°

Step-by-step explanation:

The 3 angles lie on a straight line and sum to 180° , that is

b + 43° + 90° = 180°

b + 133° = 180° ( subtract 133° from both sides )

b = 47°

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
