How to Identify Complementary Angles: Example 2 In the diagram below, {eq}\overline{HI}\perp\overline{JK} {/eq}. Find all angles that are complementary to {eq}\angle PNQ {/eq}, which measures {eq}39^{\circ} {/eq}. Step 1: Let {eq}\alpha {/eq} stand for the given angle {...
If the wall (opposite) side is 10 feet, and the ground (adjacent) side is 5 feet, the formula for the tangent angle is the opposite side divided by the adjacent side. This is 10 divided by 5, or 0.5. To find the value for the angle, you need to take the arctangent of 0.5. F...
When you choose which of the two angles (ø) in a right triangle you want to find, you establish three sides in relation to it. The line that touches the angle and extends to the 90-degree angle is called the adjacent side, while the side opposite the angle is the opposi...
Finding Angle Measures Given 2 Intersecting Lines Step 1:Read the given problem, look at the given figure of intersecting lines, and identify the angle given and the unknown angles. Step 2:Identify the angle that is vertically opposite to the given angle. Find the measure of that angle by ...
How to find the height of a triangle A triangle's height is the length of a perpendicular line segment originating on a side and intersecting the opposite angle. Every triangle has three heights, or altitudes, because every triangle has three sides.In...
. The legs of a trapezoid are equal in length, as are the diagonals. In an isosceles trapezoid, angles that share a base have the same measure. Supplementary angles, which are angles adjacent to opposite bases, have a sum of 180 degrees. These rules can be used to calculate an angle....
Step by step guide to finding missing sides and angles of a Right TriangleBy using Sine, Cosine or Tangent, we can find an unknown side in a right triangle when we have one length, and one angle (apart from the right angle). Adjacent, Opposite and Hypotenuse, in a right triangle is ...
Before you ask how to find the right hat, you first need to ask yourself “What kind of face shape am I working with?” Knowing how to find a hat for your face shape has two significant parts. First, measure your head by using a measuring tape or something flexible. A headphone set...

To find the height of a rhombus, use the formula height = area ÷ base. If you know the diagonals of a rhombus but not its area, use the formula area = (d1 x d2) ÷ 2, then apply the area to the first formula.
