Answer:

Step-by-step explanation:

The cosine of an angle is the length of the adjacent side, in this case x, divided by the length of the hypotenuse, in this case 85. So you can set up the following equation:

$\cos 64.2^{\circ}=\dfrac{x}{85}$

$x\approx 37$ units

Hope this helps!

The area of a circle is 25л ft². What is the circumference, in feet? Express your answer in terms of π.

Ahat [919]

Answer:

C = 10π ft

Step-by-step explanation:

the circumference (C) of a circle is calculated as

C = 2πr ( r is the radius )

to find r use the area formula, that is

A = πr² = 25π ( divide both sides by π )

r² = 25 ( take square root of both sides )

r = $\sqrt{25}$ = 5

then

C = 2π × 5 = 10π ft

Write out the equation: The difference of a number m and 30 is 10

inna [77]

M-30=10
It could also be 30-m=10
The answer for the first one would be 10+30=m
m=40
The answer for the second one would be 30-10=m
m=20

Hope this helps :)
