An exterior angle of a triangle is equal to the sum (far away) angles. x + y = w. P.3-L3 P.P. Key. 7) If the area of a trapezoid is 48, and the bases 1 are 10 and 6, find the height of the trapezoid. c) 6. 8) In triangle ABC, the measure of angle A is 60 degrees. If the measure of angle B is two times that of Angle C, we can conclude that:
Answer: All triangles are similar when the corresponding angles are congruent. The similar triangles have same shape but they have different size.

Then state the number of sides with equal ...
The 3 angles of a triangle has a sum of 180 so the 3rd angle is 180 - 64 - 65 = 51. Finally, straight line with 51 so it is 180 - 51 = 129. The angle that forms a straight line with 89 is 180 - 89 = 91. Then the 3 angles of the triangle I have shaded have a sum of 180. So x = 180 - 91 - 41 = 48.
