Magazine Problem 3
\(\angle 1\) is complementary to \(\angle 3 .\) If \(\angle 3=y^{\circ}\), how large is \(\angle 1 ?\)
Problem 4
Find the complement of a \(61^{\circ} 21^{\prime} 13^{\prime \prime}\) angle.
Problem 4
One of two supplementary angles is four times the other. Find the larger angle.
Problem 5
One of two complementary angles is \(20^{\circ}\) larger than the other. Find the measure of each.
Problem 5
One of two complementary angles is twice the other. Find the measures of the angles.
Problem 5
On a graph, point \(A\) is at \((0,4)\). Point \(A\) is then rotated \(90^{\circ}\) clockwise about the origin to point \(A^{\prime}\). What are the coordinates of A'?
Problem 8
The complement of an angle is \(24^{\circ}\) greater than twice the angle. Find the measure of the complement.
Problem 9
You are the engineer for the development of a new subdivision in your town. When you design your street intersections, is it better to make the intersections perpendicular or oblique? Explain why. Note When two lines intersect and are not perpendicular, they are called oblique lines.
Problem 11
One of two supplementary angles is \(70^{\circ}\) greater than the second. Find the measure of the larger angle.
Problem 13
If a pair of vertical angles are supp., what can we conclude about the angles?
