Answer:

x = 6

PM = 50

MQ = 50

PQ = 100

Step-by-step explanation:

The two halves of the segment are the same length:

PM = MQ

7x +8 = 5x +20

2x = 12 . . . . . . . . . subtract 5x+8

x = 6 . . . . . . . . . . . divide by 2

PM = 7(6)+8 = 42+8

PM = 50

MQ = 5(6) +20 = 30+20

MQ = 50

PQ = PM +MQ = 50 +50

PQ = 100

In APQR, P = 83°, p = 285 m, r = 216 m.<br>Calculate R.

vladimir1956 [14]

Answer:

48.8°

Step-by-step explanation:

We solve using sine rule

The formula is given as

p/sin P = r/sin R

In APQR, P = 83°, p = 285 m, r = 216 m.

Calculate R.

Hence, solving for R

285/sin 83 = 216/sin R

Cross Multiply

285 × sin R = sin 83 × 216

sin R = sin 83 × 216/285

R = arc sin (sin 83 × 216/285)

R = 48.78527°

Approximately = 48.8°

Therefore, R = 48.8°

We are given that a force of 60 N is exerted at an angle of 37°. Therefore, the force vector F can be represented as the hypoten

maw [93]

We are told that the force of 60 N is exerted at an angle of 37°. Since this one is on the terminal side therefore this force must be the resultant vector. We know that the resultant vector is equal to the hypotenuse of the triangle. So we can say that:

|F| = 60 N

So we see that the given angle is simply something to trick us since we are simply asked for the hypotenuse. If we are to compute for the vertical and horizontal components, that is the time we need to use the angle.

Answer:

|F| = 60 N
