Answer:

-3 1/2 + ( -6 1/2) = -10

5/8 - {-2/8} = 7/8

- 9/10 - 2/5 = -4

6 3/5 - (-2 1/5) = 44/5

Step-by-step explanation:

-3 1/2 + ( -6 1/2) = -7/2 + (-13/2) = -20/2 = -10

5/8 - {-2/8} = 5/8 + 2/8 = 7/8

- 9/10 - 2/5 = -18-2/5 = -20/5 = -4

6 3/5 - (-2 1/5) = 33/5 + 11/5 = 44/5

[Right Triangles Only] tanθ = opposite over adjacent

Step-by-step explanation:

Step 1: Identify Variables

Angle θ = x°

Opposite Leg = 10

Hypotenuse = 21

Step 2: Solve for x

Substitute [tangent]: tanx° = 10/21
Inverse trig: x° = tan⁻¹(10/21)
Evaluate: x = 25.4633°
Round: x ≈ 25.5°
