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
Answer:
8 inch
Step-by-step explanation:
dilation actor = 4/5
Scale dilation is used to change the dimensions of the line segment or anuy measurement in length.
So, 10 inch segment = inch
