Answer:
17.2
Step-by-step explanation:
We need to use the law of sines
sin A sin B
------------ = ----------
a b
sin 25 sin 27
------------ = ----------
16 x
Using cross products
x sin 25 = 16 sin 27
Divide each side by sin 25
x = 16 sin 27 / sin 25
x =17.18772863
Rounding to the nearest tenth
x = 17.2
Height:shadow=2.5:3
2.5/3=6.7/x
cross multiply aka times both sides by 3x
2.5x=20.1
divide both sides by 2.5
x=8.04
answer is 8.04ft
Answer:
-7y > 161
7y < -161
y < -23
7y > -161
y > -23
So, your answer is: -7y > 161 is equal to y < -23, and 7y > -161 is equal to y>-23.
