The angle measures of triangle ABC are given:

The measure of angle A is (2x−10)°.
The measure of angle B is 70°.
The measure of angle C is (4x)°.
What is the value of x?
If you could help asap it'd mean a lot, thanks :'D

Respuesta :

x=20
since all of the angles will add up to 180, you will add all three of the values you were give, and make it equal to 180. it will look like this: 2x-10+70+4x=180
when you simplify you should get x equals 20
you can check your work by plugging 20 in for x and then solving, and you should get 180=180
