The angles of a triangle are 80º, 2x + 2º, and 5xº. What is the value of x?
Lady bird [3.3K]
If you add 5x to 2x+2 you will get 7x+2. You would set this equation equal to 80, so it would be 7x+2=80. When you solve this you will get 11.1428571429, which can be rounded to 11, 11.1, or 11.14, whichever you prefer.

Leni [432]
First you can count multiples of 7 all the way up to 84. 7,14,21,28,35,42,49,56,63,70,77,and 84.
Or you can do 7 x 12 equals 84.
Second write down the long division way 84/7.
7 goes into 8 one time write 7 at the top then write one at the bottom bring down the 4 and make it 14
you know 7 x 2 = 14 so 12 x 7 equals 14.
