Find the value of x?
Deffense [45]

Answer:

145°

Step-by-step explanation:

See the attachment.  Angles A, B, and C all belong to the triangle.

We know that A + B + C = 180° since the angles of a triangle always add to 180°.  We also know that when two lines meet that their sum is also equal to 180°.  So we can write for each interior angle the following:

                                    <u>  Result</u>

<A = (180 - 88)                72

<B = (180-x)                  180-x

<C = (180 - 127)               53

The sum of angles A, B, and C is equal to 180:

 72 + (180-x) + 53 = 180

<h2><u>x = 145</u></h2>

Find the area of a slice of a 16 inch pizza that is cut into 8 slices
VARVARA [1.3K]

Answer:

≈ 25 in²

Step-by-step explanation:

The general formula for the area of a circle is:

A=πr²

A = (3.14)(8²)

Since the size of the pizza is 16 inches across, the radius is half of that, or 16÷2 = 8 inches.

A ≈ 201 in²

Since there 8 slices of pizza, you can take the total area and divide by 8:

201 ÷ 8 ≈ 25 in²

Find x. Round to the nearest degree.
jeka94

The Law of Cosines features the 3 side lengths of a triangle, plus the measure of the angle opposite one of those sides.


We want angle x, which is opposite the side of length 39.


Then: a^2 = b^2 - 2ab cos C becomes 39^2 = 36^2 + 59^2 - 2(36)(59)cos x


or 1521 = 3481 + 1296 - 2(36)(59) cos x


Subtract (3481+1296) from both sides: 1521 - 4777 = -4248cos x

-3256 = -4248cos x

-3256

Then: cosx = --------------- = 0.766

-4248


Solving for x: x = arccos -0.766 = 0.698 radian, or 40 degrees (answer)
