Answer:
Original number we'll call "x".
2x + 14 = 17.2
x = 1.6
Step-by-step explanation:
Given: cos A = 5/13 = adj side / hypotenuse
The the opp side is given by (hypo)^2 = (adj)^2 + (opp)^2. Here,
13^2 = 5^2 + (opp)^2, so that
(opp)^2 = 169 - 25 - 144. Then opp = +12. All of these lengths are in Q I.
opp 12
Then sin A = -------- = -------- (answer)
hyp 13
True, this is a Pythagorean identity.
Answer:
Step-by-step explanation:
We are using proportions.
Width(model) / Width(actual)
=18.5 / 370
=1 / 20
The actual building is 20 times larger than the model.
Now multiply the height of the model by 20 to get the answer.
36.5 * 20= 730ft
The answer is 730 feet
