- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>
Step 1: Define</u>
3(x + 7)° = 63°
3(x + 7)° + 63° + y° = 180°
<u>Step 2: Solve for x
</u>
- Divide 3 on both sides: x + 7 = 21
- Subtract 7 on both sides: x = 14
<u>Step 3: Solve for </u><em><u>y</u></em>
- Substitute in <em>x</em>: 3(14 + 7) + 63 + y = 180
- (Parenthesis) Add: 3(21) + 63 + y = 180
- Multiply: 63 + 63 + y = 180
- Combine like terms: y + 126 = 180
- Isolate <em>y</em>: y = 54

Answer:
y=2x-4
Step-by-step explanation:
y-y1=m(x-x1)
