We are given with the slope of a ramp that is equal to 2/5, that is x = 5 and y = 2. In this case, we can find the angle of elevation by using the formula: tan Ф = y/x
using a calculator (inverse tangent or arctangent), Ф = 21.8 degrees. In this case, the answer is D. 22 degrees.
Answer:
60
Step-by-step explanation:
Since 30%/3 is 10%, 6 is 10% of the total number of garden beds, since 18/3 is 6.
And 10% times 10 is 100%, or all of it, so 60 is the total amount of garden beds, since 6 times 10 is 60.
Answer:
it would be 7 and 8
Step-by-step explanation:
Answer:
Step-by-step explanation:
x=5
because it is an isosceles right triangle , as we have and angle of 45 and one of 90
y is the hypothenuse of the triangle
y^2=(5)^2+(5)^2=50+50=100
y=10
the larger triangle is 30-60-90
side opposite of 90 degrees is 2y
r=20
side opposite of 60 degrees is y
z=10
Answer:
5/16
Step-by-step explanation:
It's a little easier when you write the problem like this:
3 5
----- · -----
8 6
Now reduce that 3/6 to 1/2:
1 5
----- · ----- = 5/16
8 2
