First, we should add 1 to both sides to isolate the variable:
3x = 12
Now that x is isolated, we divide by 3:
x = 4
Answer:
7/5
Step-by-step explanation:
reciprocal means flip the equation
Answer:
Part A = 90
Part B = 145
Step-by-step explanation:
For part A, we know that a triangle has a sum of 180 degrees. So we just add the angles we already know and then subtract them from 180. For part B, we know that angle ACB and angle ACD are supplementary angles, meaning they add up to 180 degrees. So just take 180 and subtract 35 to find the measure of angle ACD.
I’m pretty sure it’s chad
B. looks like the way to go.
