Find the values of the variables and the measures of the angles

Answers

Answer 1

Answer:

Add each given variable

(6x + 10) + (x + 2) + x = 8x + 12

The sum of all the angles equals 180ᴼ

8x + 12 = 180

Subtract 12 from both sides

8x = 168

Divide by 8 on both sides

x = 21

Now plug in 21 for each x to find the measure of each angle.

(6[21] + 10) = 126 + 10 = 136ᴼ

(21 + 2) = 23ᴼ

x = 21ᴼ

Find the value of cos 7pi/6

Answers

The value of cos 7pi/6 = -√3/2.

$cos 7 /6= cos ( + /6) = cos (/6) = -√3/2.$

What is the value of cos?

cos The value of 1 degree is 0.9998476. .. .. Cos 1 degree radians are written as cos (1 ° x π / 180 °). H. cos (0.017453. .. .. ). This article describes how to find the value of cos1 using an example. Cos1 °: 0.9998476.

Trigonometric functions, fields of mathematics related to specific trigonometric functions, and their computational applications. There are six trigonometric functions commonly used in trigonometric functions. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), second (sec), and cosecant (CSC).

A function of arc or angle (sine, cosine, tangent, cotangent, second, cotangent, etc.) is most easily expressed by the ratio of the pair of sides of a right triangle.

D.
240 square feet

Answers

To find the area of the trapezoid you add the two bases then multiply by the base and divide by 2.

B1+b2= 24+16=40
40*h=40*12=480
480/2=240

D. 240 square feet.
