Alrighty.
First we need to make them all simplified.
So simplified would be $\frac{9}{10}$ times $\frac{5}{4}$ times $\frac{5}{2}$ .
Then we multiply the numerator and the denominator. The final answer is $\frac{225}{800}$
Simplified is $\frac{51}{160}$

The resultant of a 15 pound force and an 8-pound force acting on an object is 10 pounds.

natali 33 [55]

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 $\alpha$ ,

2*10*8*cos $\alpha$ = $8^{2} +10^{2} -15^{2} = 64+100-225= 164-225=-61$

now, dividing both sides by 2*10*8,

cos $\alpha$ = -61/160

$\alpha$ = 112.4 degrees = 112 ( appox) ( use calculator for this cos inverse function)
