It is: 180-(2*53) = 74 degrees.
(Note that the side length doesn't matter.)

If the vertex of an isosceles triangle has a measure of 70° what is the measure of one base angleANSWER:Isosceles = 2 legs, 1 vertex, 1 baseTriangle = 180°if its vertex measure 70° , 1 leg ____? + 1 leg____? =180° and all isosceles triangle has congruent legs.180°- 70°=110° then 110° divided by 2 =55°=vertex of an isosceles triangle measure 70° and its 2 legs measure 55°
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
Each base angle is 62.5 degrees
It is an isosceles triangle if 2 sides measure 25 feet and the other side measures 10 feet
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
There is no exact measure, but 2 sides are congruent which means that 2 angles are congruent.
congruent/equivalent in measure
Each of the base angles measure 71 degrees
(180 - 36) / 2 = 72

A scalene triangle. In a scalene triangle, there are no congruent sides or angles. In an isosceles triangle, at least two congruent sides and angles. In an equilateral triangle, all three sides and angles are congruent, with angles that always measure sixty degrees. Note: an equilateral triangle also classifies as an isosceles triangle, as it meets the definition of an isosceles triangle mentioned above.

Well, I know the other angles are 71. But idk how to get the base. cause inside, a triangle must be 180 degrees. so you take 180 - 38, and get 142. then you take 142 divided by two, because in an isosceles triangle two sides are congruent. then you get 71. The legs are 21, but what's the base?!
No. The only requirement for a triangle to be a 45-45-90 triangle is for it to have at least two congruent sides/angles. The measure of the two congruent angles can be anything.
Length of sides is irrelevant. Angles are ((180 - 40)/2) ie 70o
