Find value of each variable! Express in simplest radical form!

Mathematics
1 answer:
Papessa [141]3 years ago
3 0

Step-by-step explanation:

3. The triangle that makes up the square is a 45-90-45 triangle so x = 45°. Using Pythagorean theorem,

2y^2 = 12 ---> y^2 = 6

or

y = √6

4.This is an equilateral triangle of side 11 so

y = 11/2

To find x, use the definition of sine 60:

sin 60° = opp/hyp

= x/11

or

x = 11sin60° = (11√3)/2

A rectangle is 8 feet long.its width is represented by Seven plus x feet what expression
babunello [35]
Hi there! The answer is 56 + 8x square feet

The length of a rectangle is 8 feet.
The width of that rectangle is 7 + x feet.

We can find the area of the rectangle by using the formula A = L x W
(Area = Length x Width)

Filling in this formula gives us:
A = 8 (7 + x) = 56 + 8x square feet

The volume of a sphere is 972(pi)ft3.
pav-90 [236]

Here are some simple equations that can be a life saver with this stuff :

vol of a sphere =

v = \frac{3}{4} \pi \: {r}^{3}

Circumference =

2 \times \pi \times r

sorry this might not be very helpful. I haven't don't this since last year. You basically have to work backwards. so plug in 972 for V and then do (3/4)×3.14.

then take the answer u got for ^^ and divide it by 2? not sure.
