What is the measure of the vertex angle of an isosceles triangle if the base angles measure 56 degrees?
If each base angle is 56°, then the vertex angle is 68°.If both base angles combined total 56°, then the vertex angle is 124°.
What is the measure of the vertex angle of an isosceles triangle if one of its base angles measures 58?
One of the base angle is 58 deg so the other base angle is 58 deg. Sum of all three angles is 180 deg so the third angle (the vertex angle) is 180 - 58 - 58 = 64 degrees.
What do vertical angles add up to?
A vertical angle is perpendicular to a horizontal base and equals 90 degrees
What is the measure of the vertex angle of an isosceles triangle if one of its base angles measures 42?
If you are dealing with an isosceles triangle, if one of the base angles measures 42 degrees then the other base angle measures 42 degrees. (By definitioin an isosceles triangle has at least 2 equal sides and the angle opposite those sides with be equal.) If you add up the degrees in each angle within a triangle, it will always equal 180 degrees. Knowing all this you can set up a formula: Angle 1 + Angle 2 + Angle 3 = 180 42 + 42 + Angle 3 = 180 Angle 3 = 96 degrees
What is the measurement of each base angle 6x plus 8 and 9x - 25?
As presented, the question cannot be answered. But if you assume - however unjustified such assumptions are - thatthe triangle is isosceles andthat these are the two base angles, thenthen each base angle is 74 degrees.
What is the measure of base angle if vertex angle of an isosceles triangle is 80?
The base angles will have equal angles of 50 degrees
What are the measures of the Base angles of an isosceles triangle whose vertex angle has measure of 70?
All angle sum to 180 degrees. Take 70 from this which leaves 110 degrees. The base angles must be equal so halve this number. Base angles are 55 degrees.
Can a base angle of an isosceles triangle be a right angle?
No but its apex angle can be a right angle with 2 equal base angles of 45 degrees
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 each angle of an isosceles triangle if the measure of the third angle is 7 times the measure of either of the two base angles?
The angles are 140 degrees, 20 degrees and 20 degrees that add up to 180 degrees
What is the base angle of an isosceles triange with a vertex of 40 degrees?
It will have two equal base angles of 70 degrees.
What is the measure of the vertex angle of an isosceles triangle if the base angles measure 56 degrees?
If each base angle is 56°, then the vertex angle is 68°.If both base angles combined total 56°, then the vertex angle is 124°.
If the vertex angle of an isosceles triangle is 106 degrees what is the measure of each base angle?
The sum of all three angles is 180 degrees. So the two base angles add to 180 - 106 = 74 degrees. The two base angles are equal so each is 74/2 = 37 deg
What are the measures of the Base angles of an isosceles triangle whose vertex angle has measure of 55?
Each base angle is 62.5 degrees
The obtuse angle of an isosceles triangle measures 120 degrees write and solve an equation to find the measure of the base angles?
Well if it has 180 degrees over all, and the two base angles have to be congruent, then the equation is 180-120=2x or each base angle is 30 degrees.
What is the measure of the vertex angle of an isosceles triangle if one of its base angles measures 53?
If your "53" is in degrees, then the vertex angle is 74 degrees.
What is the measure of the vertex angle of an isosceles triangle if one of its base angles measures 75 and its congruent sides each measure 15 cm?
The length of the congruent sides is irrelevant. If one of the base angles is 75 deg, the two base angles sum to 150 degrees. Since the sum of all three angles is 180 degrees, the third angle, the vertex angle, must be 180 - 150 = 30 degrees.
