Answer:
Step-by-step explanation:
<u>Sum of angles in triangle equals to 180°</u>
- ∠R = 180° - (∠S + ∠T)
- ∠R = 180° - (29° + 61°) = 180° - 90° = 90°
Answer:
linear, 264*2 = 528
Step-by-step explanation:
Answer:
x = 22
3x + 2 = 68°
Step-by-step explanation:
x + 3x + 2 = 90° because this is a right triangle
3x + 2 = 90
4x = 88 divide by 4
x = 22
3x + 2 replace x with the value we found
3×22 + 2 = 68°
