Answer:
x = -10
Step-by-step explanation:
y = 2x + 5
-15 = 2x + 5
-20 = 2x
-10 = x

[Right Triangles Only] tanθ = opposite over adjacent<u>
</u>
Step-by-step explanation:
<u>Step 1: Identify</u>
Angle θ = 50°
Opposite Leg = 7
Adjacent Leg = BC
<u>Step 2: Solve for BC</u>
- Substitute in variables [tangent]: tan50° = 7/AC
- [Multiplication Property of Equality] Multiply AC on both sides: ACtan50° = 7
- [Division Property of Equality] Isolate AC: AC = 7/tan50°
- Evaluate: AC = 5.8737
- Round: AC ≈ 5.87
