Find The Measure Of Each Interior Angle In Triangle Vio. 70 32 x 180. Mangle Amangle Bmangle C180 Plug in the measure for all these angles by using substitution.
The other angle 5x 515 75º sum of angles in a triangle is 180 the last angle 180 - 45 - 75 60º. E F G 86. A b c 180 a b c 180.
Since the interior angles add up to 180 every angle must be less than 180.
The measure of one angle is given the other two angles are represented by algebraic expressions like 5x and x 7. 1 4 7 3 6 9 2 5 8 T U V 63. E F G 86. Sum of the Interior Angles of a Triangle Worksheet 2 RTF Sum of the Interior Angles of a Triangle.
