Step-by-step explanation:
<u>Step 1: Define equation</u>
4x - 5 = x - 1 + 3x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 4x - 5 = 4x - 1
- Subtract 4x on both sides: -5 ≠ -1
Here we see that -5 does not equal -1.
∴ This equation has no solutions.
(180-x)-2(90-x)= 53
Remember that complimentary angles add to 90 and supplementary angles add to 180.
180-x-180+2x=53
x=53
Final answer: The angle is 53 degrees.
