Answer:
70.1 ft
Step-by-step explanation:
The cosine relation gives the ratio of the adjacent side to the hypotenuse for an acute angle in a right triangle:
Cos = Adjacent/Hypotenuse
cos(37°) = SQ/QR
Rearranging gives ...
QR = SQ/cos(37°) = (56 ft)/0.798636 = 70.1 ft
The length of QR is about 70.1 ft.
Answer:
Step-by-step explanation:
Just read it from left to right
13*155 = 2015
2015/26 = 77.5
You could also cancel the 13 and 26. If you do, you get
155/2 = 77.5
Either way works.
