    review triangles 2 equal sides/angles = isosceles 90 degrees = right angle 3 different lengths = scalene 3 equal sides/angles = equilateral less than 90 = acute more than 90 = obtuse

    one approach write the expression for the sum of the angles set = 180 solve for x find the value of the angles

    is the answer 42?

    180 -<5 = < 4 180 - (<2 + <3) = <4 <4 = <4 180 -<5 = 180 - (<2 + <3) therefore <5 = (<2 + < 3)

    are you mixing the questions? for the first one the angles were 46, 42 and 92 different angles so scalene triangle

    for the 2nd question which interior angles have the same value as angle 5? note that angle 1 has the same value as < 5 corresponding exterior angles

    so <2 and <3 are the remote interior angles to <5
