180 - twice 42
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.

69 degrees 180-42 = 138 138/2 = 69 degrees You do not need the measure of the side to derive the answer.
To find the measure of angle HLJ, we can use the fact that the sum of the angles in triangle HLI must equal 180 degrees. Therefore, angle HLJ can be calculated as follows: Angle HLJ = 180° - (angle ILJ + angle HLI) = 180° - (42° + 45°) = 180° - 87° = 93°. Thus, the measure of angle HLJ is 93 degrees.

If two chords intersect inside a circle, the acute angle they form is one half of the sum of the arcs intercepted by its sides and by the vertical angle SO... The acute angle will be one half the sum of the two arcs. So it is 1/2(42+94)=68 degrees.
90 - 42 ie 48o
It is: 180-42 = 138 degrees
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.
