Question

An isosceles triangle has an angle that measures 134°. Which other angles could be in that isosceles triangle? Choose all that apply. 23 20 72 81

Answer 1

An isosceles triangle with an angle measuring 134° can have other angles measuring 46° each.

Step-by-step explanation:

An isosceles triangle has two equal angles and one angle that is different. We know that the sum of the three angles in a triangle is always 180°. Since one angle is given as 134°, the other two angles must be equal. To find the value of those angles, we can subtract 134° from 180° and divide the result by 2. So, (180° - 134°) / 2 = 46°.

Therefore, the other two possible angles in the isosceles triangle are 46° each. So the correct options from the given choices are 23 and 72.

Answer 2

23

Step-by-step explanation:

one angle = 134

Other two angles are the base angles which are same.

x + x + 134 = 180 {Angle sum property}

2x + 134 = 180

2x = 180 - 134

2x = 46

x = 46/2

x = 23

Other two angles are 23 , 23
