Answer:
sin θ = 24/25.
Step-by-step explanation:
Cos θ = 7/25 so we have a right triangle with adjacent side = 7 and hypotenuse = 25.
So the opposite side = sqrt ( 25^2 - 7^2) ( By Pythagoras)
= sqrt 576
= 24 .
Therefore sin θ = 24/25.
Answer:
Length of the garden = 69.28 meters.
Step-by-step explanation:
See the attached diagram.
Let CD is the pole with a height of 30 m and the elevation of the top of the pole from the endpoints of the length A and B are 60° and 30° respectively.
So, ∠ DAC = 60° and ∠ DBC = 30°
Now, Δ ACD is a right triangle and
⇒
meters.
Now, from Δ BCD which is a right triangle,
⇒
meters.
Hence, AB = AC + CB = 17.32 + 51.96 = 69.28 meters. (Answer)
Answer:
$180,000
Step-by-step explanation:
Because the artist gets 20% of the retail price, and 20% is equal to 1/5, the artist gets 1/5 of the retail price. So you do 36,000 times 5 to get the whole, original price.
The first one is B
Second there is no answer
Third is A
Do you want an explanation?
I posted how to do the first and third question. The second question is by combining like term. X^4 plus 2x^4 is 3x^4, x plus 4x is 5x and there is -3x^3 and -7. That makes the answer 3x^4-3x^3+5x-7. Sorry for the sloppy handwriting.
EDIT: I apologize for getting the second question wrong in the beginning.
