Answer:
Hector's kite is 61.84 feet from the ground.
Step-by-step explanation:
The angle of elevation of the kite is 42°15’30” when converted to decimals, it is
≅ 
Let the height of the kite to the horizontal of angle of elevation be represented as x. Applying the trigonometric function to the sketch of Hector's kite,
Sin θ = 
Sin
= 
⇒ x = 86 x Sin 
= 86 x 0.6725
= 57.835
x ≅ 57.84 feet
The height of Hector's kite from the ground = x + 4
= 57.84 + 4
= 61.84 feet
Answer:
Its either C. or D.
Step-by-step explanation:
Answer:
289π ft²
Step-by-step explanation:
a=π×r²
r=17
π=3.14
17²=289
She spent 25% and had $99 left.
$99 is 75% of the remaining money.
Divide to find the total remaining
99 / 0.75 = $132
Now she put 80% of her total earnings in the bank, this means the remaining amount is 20%.
Divide the remaining amount by 20%:
132 / 0.20 = $660
She earned $660 total.
