The drawing shows a cross section of a saw blade which has teeth whose edges are parallel to each other.If angle B is 210, calculate the size of angle C.

A carpenter is making a rectangular picture frame. Two of the boards which form a right angle are shown in the sketch below.If angle A is 420 what is the measure of angle B?

This image shows right triangle A B C where A is the right angle. Line segment D E intersects side A B perpendicularly at point D to create a smaller right triangle B D E. Angle B E D measures 60 degrees. Side A B measures (5 times square root 3) units. Side B C measures 'x' units.What is the value of   in the figure shown?

A square-cut end of a 1-by-8 piece of wood must be re-cut at a slant. To make the angle of the slant 104o, what angle must be cut off 90o?(In other words, how large is angle ?)

Erin is working on a project for her high school carpentry class. She cuts the top end of a peice of wood at an angle. The vertical sides of the piece are parallel to each other. The measure of the angle between the left vertical side and the top end equals 114o. What must the measure of the angle between the right vertical side and the top end equal?(Enter the number only with no degree symbol in the blank.)

Find the measure of the reference angle for a 170° angle.
