The sum of all angles in a triangle sum up to 180.
∠1 = x+37
∠2=x+67
∠3=90° (right triangle)
∠1+∠2+∠3 = 180°
(x+37)+(x+67)+90=180
2x+104+90=180
2x+194=180
2x=-14
x=-7
An angle can't be negative, but when plugged in it works!!
∠1 = -7+37=30
∠2=-7+67=60
30+60+90=180
Hope it helps!
C never, there are always different methods to solve a problem but don't forget that the equation always stays the same!
Step-by-step explanation:
2x + 5 (y-1)

Answer:
x = 2/5
General Formulas and Concepts:
Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Write equation</u>
5x = 2
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide both sides by 5: x = 2/5
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution</em>.
- Substitute: 5(2/5) = 2
- Multiply: 10/5 = 2
- Divide: 2 = 2
