Solve exterior angle of triangle
WebMar 1, 2010 · Since the sum of the angles in a triangle is always 180 degrees, you should first take the sum of the other two angles and then subtract this from 180 in order to find the measurement of the missing angle in the triangle. Next, since there are also 180 degrees in a straight line, you should subtract this new number from 180 in order to get your ... Webtriangle below right. Part 1: Model Problems Example 1: Determine the unknown angle in the triangle pictured below: Step 1: Set up an equation to represent the situation: Since the three angles must sum to 180°, we write x 82 45 180 Step 2: Solve for the unknown variable: q 53 127 127 127 180 x x Step 3: Check for reasonableness: Since

WebThe 71 degree angle that we just found forms a linear pair with the exterior angle. This means that these two angles must add up to 180 degrees. We can subtract 71 from 180 to find the measure of the exterior angle. This gives us 109 degrees for the exterior angle. Now look back at the picture. WebJan 26, 2024 · We can use two different methods to find our missing angle: How to Find the Angle of a Triangle. Subtract the two known angles from 180°: 180°-37°=143° 180° − 37° = 143°. 143°−24°=119° 143° − 24° = 119°. c=119° c = 119°. Plug the two angles into the formula and use algebra: a + b + c = 180°. 37°+24°+c=180° 37° + 24 ...
