Two forces with magnitudes of 150 and 75 pounds act on an object at angles of 30° and 150°, respectively. Find the direction and
Anastaziya [24]
The problem is modelled in the first picture shown below

To work out the resultant vector, we modelled the vectors 150N and 75N as triangle AOB is shown in the second picture with AB as the resultant vector. 

We use the cosine rule to work out the length AB
AB^{2}= 75^{2}+ 150^{2}-(2*75*150*cos(60))
AB^{2} =28125-11250
AB^{2}=16875
AB= \sqrt{16875} =130(nearest whole number)

The third picture shows the full diagram of the vectors

To work out the direction of the resultant vector, we use the sin rule to find the size of angle A and angle B

Angle A
\frac{130}{sin(60)}= \frac{75}{sin(A)}
130sin(A)=75sin(60)
sin(A)= \frac{75sin(60)}{130}
sin(A)=0.4996300406
A= sin^{-1}(0.4996300406)
A=30 (rounded to nearest whole number)

Angle B
B=180-60-30=90

Direction is 60° toward negative x-axis

Answer: Magnitude 130N and direction 60° toward negative x-axis

A circle is centered on point B. Points A, C and D lie on its circumference.
IRISSAK [1]

Given:

A circle is centered on point B.

Points A, C and D lie on its circumference.

If m\angle ABC measures 40°.

To find:

The m\angle ADC.

Solution:

Central angle theorem: According to this theorem, the central angle is equal to the twice of inscribed angle on the same intercepted arc.

In the given figure \angle ABC is the central angle and m\angle ADC is the inscribed angle on the same arc AC.

Using central angle theorem, we get

m\angle ABC=2m\angle ADC

40^\circ=2m\angle ADC

\dfrac{40^\circ}{2}=m\angle ADC

20^\circ=m\angle ADC

Therefore, the measure of angle ADC is 20°.
