You do 5-3 and you get 2 then divide 42 by 2 and your answer is 21
We will be using the cosine function to figure this out.
The ramp, ground, and platform form a right triangle.
The hypotenuse is 29, and the side adjacent to ∠x is 20.
SO:
Cos ∠x = 20/29
Cos ∠x = 0.68965517241379
Use the function on your calculator to find what angle has a Cos of 0.6896551
Cos 0.6896551 = 46.397°
ANSWER: the angle of elevation is 46.4°
Hope this helps! God bless. :)
Answer:
1.) a= √50
2.) a = (10√3)/3
3.) a = 6
4.) a =√5
5.) a = (3√2)/2
6.) a =2
7.) a=12
8.) a= 3√3
9.) a= 6√2
10.) a= 2√3
11.) a= 2√2
12.) a=8
Step-by-step explanation:
30-60-90 triangles
hypotenuse = 2(short leg)
short leg = 1/2(hypotenuse)
long leg = short leg(√3)
short leg = long leg/√3
45-45-90 triangles
hypotneuse = leg(√2)
Answer:
$42.12
Step-by-step explanation:
35% off means she has to pay:
100 - 35 = 65% of the marked price.
65/100 × 60 = 39
Tax: 8%
8/100 × 39 = 3.12
To pay:
39 + 3.12 = 42.12
They're equal length, so add 18 and 18 to get 36.
