What is the measure of a base angle of an isosceles triangle if the measure of the vertex angle is 42 and two congruent sides each measure 21 units?
The length of the congruent sides makes no difference to the measured angles. Assuming the base angles are the congruent angles, then: angle = (180o - other_angle) ÷ 2 = (180o - 42o) ÷ 2 = 69o
What is the measurement of the vertex angle of an isosceles triangle is the measure of one of its base angle is 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.
What is the measure of a triangle's third angle if 2 angles are each 42 degree?
96 degrees
What is the measure of a base angle of an isosceles triangle if the measure of the vertex angle is 42 and the two congruent sides each measure 21 units?
69 degrees 180-42 = 138 138/2 = 69 degrees You do not need the measure of the side to derive the answer.
Two observers are standing 500 feet apart Each measure the angle of elevation of a balloon that lies in a vertical plane passing through their locations The angles are 53 and 42. Height of Balloon?

Two angles are complementary - the second angle measure 42 less the first angle - What is the measure of the 1st angle?
41
One of two complementary angles has a measure that is six more than twice the other's Find the measure of the larger angle?
this is what i have: X= 6+(90-X)+2(90-X) and i got 42 degrees?
What is the angle measure complementary to 42 degrees?
90 - 42 ie 48o
What are the measures of a complementary angle if the difference in the measures of the angle is 8?
Suppose the two angles are x and y. They are complementary so x + y = 90 and their difference is 6 so x - y = 6 Adding the two equations: 2x = 96 so that x = 96/2 = 48 Then, substituting this value of x in either equation, y = 42. So the angles are 42 and 48 degrees.
What is the measure of the base angle of an isosceles triangle if the measure of the vertex angle is 42 degrees and the two congruent sides each measure 21 units?
If it is an isosceles triangle then the base angles must be equal angles of 69 degrees because there are 180 degrees in a triangle and 42+69+69 = 180 degrees
What is the measure of the third angle of a triangle if two angle measures 42 degrees?
96˚all angles to a triangle equals 180˚
What is the measure of a base angle of an isosceles triangle if the measure of the vertex angle is 42 and two congruent sides each measure 21 units?
The length of the congruent sides makes no difference to the measured angles. Assuming the base angles are the congruent angles, then: angle = (180o - other_angle) ÷ 2 = (180o - 42o) ÷ 2 = 69o
What is the sum of the measures of the angle in any triangle is 180 degrees - in triangle ABC angles A and B have the same measure while angle C is 42 degrees larger than each other two angles?
138
What is the measure of the vertex angel of an isosceles triangle if one of its base angles measures 42 degress?
Vertex angle: 180-42-42 = 96 degrees
If two of a triangle's angles measure 42 degrees and 48 degrees how would you classify that triangle?
It's important to remember that a triangle's angles will always total 180 degrees. 180 - 42 - 48 = 90. The last angle is 90 degrees, so this is a right triangle.
What is the measurement of the vertex angle of an isosceles triangle is the measure of one of its base angle is 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.
What is the measure of a triangle's third angle if 2 angles are each 42 degree?
96 degrees
