To find the measure of angle 5, we can use the relationship between the arcs and the angles they subtend. If angle 5 subtends arc BC, then the measure of angle 5 is half the measure of arc BC. Therefore, angle 5 would measure ( \frac{42}{2} = 21 ) degrees. If angle 5 relates to arc DE, further information is needed to determine its measure.

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.

32 degrees

The measure of five is 5.
ok
180 - twice 42
The measure of five is 5.
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.
