For example, given that the side corresponding to the 60° angle is 5, let a be the length of the side corresponding to the 30° angle, b be the length of the 60° side, and c be the length of the 90° side. Q. User: What are adjacent angles ? In this type of right triangle, the sides corresponding to the angles 30°-60°-90° follow a ratio of 1:√ 3:2. Which side of the triangle is adjacent to angle A? 65 plus 90 is 155. 2 and 4. alternatives ∠CXF and ∠DXE ∠CXD and ∠DXE . These are examples of adjacent angles.80 35 45. Supplementary, Complementary, Adjacent Angles DRAFT. Math. Find the measures of angles 1, 2, and 4 below given that lines m and n are parallel. Weegy: The sum of the measures of two supplementary angles is 180 degrees.If the first angle measures 60 degrees, the second angle measures 180 minus 60 = 120 … Thus, in this type of triangle, if the length of one side and the side's corresponding angle is … 7x = 126. Line A F E is horizontal. Which three angles are supplementary? Solution : Let "x" be the first angle. Edit. Q S P R O 6 Find the value of x and each angle if m
