Step-by-step explanation:
S+T+U=180°{sum of angle of triangle}
- 68°+90°+U=180°
- U=180-158°
- U=22°
sin theta= p/h
sin22°=x/83
o.37=x/83
x=0.37×83
x=30.71
x=31

1. 50 degree angle I believe
2. 150 degree angle
3. 45 degree angle
Sorry if this doesn't help but, with no context about the answers they have given you I can't fully help. Try using a protractor like this down below.
Have a good day!
Trevor’s estimate is UNDERestimate because 8*6 is 48 and 8.33*6.2 = 51.646
Answer:
B I think
Step-by-step explanation:
Answer:
1 = 4 = 38°, 2 = 3 = 90°
Step-by-step explanation:
Because the diagonals of rhombi are perpendicular, ∠2 = ∠3 = 90°. Since the sum of angles in a triangle is 180°, ∠1 = 180° - 52° - 90° = 38°. If we look at the triangle with 1 and 4 as its base angles, we notice that it's an isosceles triangle, therefore ∠1 = ∠4 = 38°.
