Answer:
3.7feet
Step-by-step explanations
Using the sin rule
A/sin a = B/sin b
Let A = PQ = 8.5feet
B = QR = x feet
a = R = 90°
b = P = 26°
Substitute the values into the Sin rule
8.5/sin90 = x/sin26
8.5×sin 26 = x × sin 90
8.5×0.4383 = x× 1
3.7255 = x
Hence the length of QR to the nearest tenth 3.7feet
The first step for solving this problem is to know that in order to divide by a fraction,, we must multiply by the reciprocal of that fraction. This will look like the following:
× 9x
Write -6x as a difference.
× 9x
Factor out x from x² + 2x.
× 9x
Factor out -8 from -8(x + 2).
× 9x
Factor out x + 2 from the denominator (bottom) of the expression.
× 9x
Reduce the fraction with x + 2
× 9x
Finally,, calculate the product to find your final answer.
This means that the correct answer to your question is going to be option B.
