Help me I don’t wanna fail mann

Answer 1

x=6

∠TSU=12x=12(6)=72

Explanation:

∠TUS+∠STU+∠TSU=180

∠TUS+12x+81=180

∠TUS=99-12x

∠TUS+∠TUV=180

99-12x+24x+9=180

108+12x=180

12x=72

x=6

∠TSU=12x=12(6)=72

There you go. Try and use these solutions to solve others for yourself. You got it.

Answer 2

• x = 6°
• ∠TSU = 72°

Explanation:

Angle TUV is exterior angle to triangle TUS. Exterior angle measure is equal to sum of non-adjacent interior angles:

• ∠TUV = ∠STU + ∠TSU
• 24x + 9 = 81 + 12x

Solving for x

• 24x - 12x = 81 - 9
• 12x = 72
• x = 72/12
• x = 6°

Finding angle measure of ∠TSU

• ∠TSU = 12*6° = 72°
