I used a calculator :)
Answer:
C. 60
Step-by-step explanation:
You can take away 120 instantly because that angle is acute. This leaves you with A, B, and C. It's most certainly too big to be C. By this point you can look at it and draw a 90 degree angle in your mind and you can see that it looks about 2/3 of a 90 degree angle.
May I have brainliest please? :)

- Coordinates (x, y)
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define System</u>
4x + 2y = -1
3x + 4y = 3
<u>Step 2: Rewrite System</u>
4x + 2y = -1
- [Multiplication Property of Equality] Multiply -2 on both sides: -2(4x + 2y) = 2
- [Distributive Property] Distribute -2 on both sides: -8x - 4y = 2
<u>Step 3: Redefine Systems</u>
-8x - 4y = 2
3x + 4y = 3
<u>Step 4: Solve for </u><em><u>x</u></em>
- Combine equations: -5x = 5
- [Division Property of Equality] Divide -5 on both sides: x = -1
<u>Step 5: Solve for </u><em><u>y</u></em>
- Substitute in <em>x</em> [Original Equation]: 3(-1) + 4y = 3
- Multiply: -3 + 4y = 3
- [Addition Property of Equality] Add 3 on both sides: 4y = 6
- [Division Property of Equality] Divide 4 on both sides: y = 3/2
