Hey there! I'm happy to help!

To find the surface area of a sphere, here is what you do.

You square the radius.

4²=16

You multiply by 4.

16×4=64

And you multiply by pi!

64×π=64π

Therefore, the surface area of the sphere is A. 64π units². It's that easy!

Now you can find the surface area of a sphere! Have a wonderful day! :D

In the figure below, angle y and angle x form vertical angles. Angle y forms a straight line with the 60° angle and the 70° angl
nirvana33 [79]

The equation that solve for x is as follows;

70 + 60 + x = 180

<h3 /><h3>How to find an angle?</h3>

The equation that can be used to find the measure of angle x can be found as follows:

60 + 70 + y = 180

Therefore,

130 + y = 180

subtract 130 from both sides

130 - 130 + y = 180 - 130

y = 50°

70 + 60 + x = 180

130 + x = 180

x = 180 - 130

x = 50°

x and y are  vertically opposite angles.

How many solutions does this linear system have y= 1/2x+4 <br> x+2y=-8
lara [203]

Answer:

1 solution

Step-by-step explanation:

y = 1/2x + 4  

x + 2y = -8

Solve the second equation for y.

2y = -x - 8

y = -1/2x - 4

The two equations in slope-intercept form are:

y = 1/2x + 4

y = -1/2x - 4

The system consists of two lines with different slopes, so they intercept at a single point which is the solution.

Answer: 1 solution

Find the missing side of this right
navik [9.2K]

Answer:

x = 13

Step-by-step explanation:

First start with the blank equation

a^{2} + b^{2} = c^{2}

Plug in the legs and hypotenuse. Remember c squared is always the hypotenuse.

5^{2} + 12^{2} = c^{2}

Then solve

25 + 144 = c^{2}

169 =c^{2}

\sqrt{169} = \sqrt{c^{2} }

c = 13
