Answer:
112 degrees.
Step-by-step explanation:
- as we know that the three set of forces will form a triangle, by using cosine rule, we can find the required angle.
- follow the diagram in the attachment.
- by cosine rule for
,
2*10*8*cos
= 
now, dividing both sides by 2*10*8,
cos
= -61/160
= 112.4 degrees = 112 ( appox) ( use calculator for this cos inverse function)
Answer:
Step-by-step explanation:
Given RT bisects QTS, so
3x+9 = 5x-3
9+3 = 5x-3x
2x = 12
x = 6
Check:
3(6) + 9 = 27
5(6)-3 = 27
