Answer: true
Explanation:
Step-by-step explanation:
3x=28+y
x=28+y÷3
then puttingx=28+y÷3
3x=14+y
3(28+y÷3)+y=14
84+3y+3y=42
3y+3y=42-84
y=-42÷6
y=7
so putting y=-7
3x-y=28
3x-7=38
x=38+7÷3
x=15
Answer:
375 meters
Step-by-step explanation:
We use the tangent ratio to determine the height of the height of the cliff.
We have that, the boat is 600 meters from the base of a cliff.
We also know that, the angle of elevation to the top of the cliff is 32°
Using the tangent ratio, we have:
We solve for h to obtain:
Therefore the height of the cliff is approximately 375 meters
