We are looking to figure out the size of m<CAB
Since line AB is parallel to the line CD, m<CAB corresponds to m<ECD which means the size of the angles equals
m<ECD can be found by using the fact that angles in a triangle add up to 180°,
hence, 180°-58°-43°=79°
The size of m<CAB is 79°
Step-by-step explanation:
Taking the first coordinate point (3,16.5)
where x= 3 and y= 16.5



optionB
Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.

Answer:
Tangents of a circle from the same exterior point have equal distances from the external point to the points of tangency. Therefore, AB is 7 inches also.
If you draw this accurately, you can actually measure the distances to verify it. Try it!
