Answer:
h ≈ 9.9 cm
Step-by-step explanation:
By applying tangent rule for the given angle in the given right triangle,
tan(51°) = 
tan(51°) =
h = 8 × tan(51°)
h = 9.879
h ≈ 9.9 cm
Therefore, measure of side 'h' is 9.9 cm.
Answer:
39. r = 13.4
40. m = 12
Step-by-step explanation:
39. Given the equation,
, to solve for r, the following are the correct steps to take to arrive at the solution:
(given)
Add 0.8 to both sides of the equation (addition property of equality)
(this is where the error occurred.)

40. The correct steps to take in solving the equation,
is as follows:
(given)
Multiply both sides by 3 (multiplication property of equality)

(this is where the error occurred. This is what we should have at this line/step)
(dividing both sides by -1)
