X^2- 11 = 70 I need help on how to solve this

±9

We are given the equation:

x² - 11 = 70

Solving for x:

x² - 11 = 70

x² = 81                                                          [adding 11 on both sides]

x = ±√81                                                 [taking the square root of both sides]

x = ±9

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

maybe showing the graph would
