Solve for x with 9x+1 and 88? i don’t know how to and i really need it. attachment has the picture.

x = 5

Step-by-step explanation:

We know that adding up all the degrees in a triangle will give you 180. So, subtracting the given angle from 180 will give us the sum of the missing angles: 180 - 88 = 92.

Since the diagram shows us that the triangle is isoscles, we know that the missing two angles are the same and equivalent. So, in order to get the value of one angle, we divide the sum of angles by 2: 92/2 = 46.

Now that we've found the value of one angle, we set it equal to the equation given to find the value of x: 9x + 1 = 46.

Last but not least, solve for x: 9x = 45 --> x = 5

mean, 40.6
