How to work this out?

A: 60

B: 1/5

C: 200

Step-by-step explanation:

For A you would divide 300 by 5.

For B you would divide 5 by 1.

For C you would divide 1000 by 5.

For problem #4 the answer is 100°. The triangle are congruent meaning the angles that are given both of the triangle have to have the same angles.

The triangle sum theorem is all triangles have a 180° . All the 3 angles = 180.

They gave you two angles of the triangle. So add the two angles and find the difference of 180.

50+30=80

180-80=100°

#5 set those 2 angles equal. Because the A corresponds to Q. Solve for X and plug in your x value
