What is the value of x, and what is the missing angle?

NO LINKS, THEY WILL BE REMOVED

x=10

B=98

Step-by-step explanation:

It will equal 82 in the end.

9×10-8

90-8

82

To find B I took 180 and subtracted 82 to get 98

Hope this helps ^-^

x=10

Step-by-step explanation:

1.) 9x-8 and 82 are equivalent, meaning they both equal earth other.

2.) So, your equation would be 9x-8=82

3.) You need to solve for x by isolating x. Firstly, you need to get rid of the -8 by making it zero. Therefore, you add 8, but you also need to add 8 to 82.

4.) You are left with 9x=90, but x is still not by itself. The operation being used that involves 9 is multiplication. We need to get 9 to equal 0 so we divided by 9 to both sides.

5.) x is finally isolated and you are left with x=10

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
