Question

if one angle of an issosceles triangle is 100°, what will be the measure of the other angle ?​

Answer 1

Answer:

One angle measure is an isosceles triangle is 100 degrees.what is the measure of each of the other two angles

-----

The sum of the angles is 180.

The 100 degree angle cannot be a base angle as then

the sum of the base angles would be 200 degrees.

---

The 100 must be the vertex angle.

---

Let the base angles be "x" and "x":

Equation:

x + x + 100 = 180

2x = 80

x = 40 degrees.

Each of the base angles is 40 degrees.

please mark me as brainlist.

Answer 2

Answer:

thank e and follow

Step-by-step explanation:

one pair of opposite angle of isosceles triangles are equal

let that angles =x

2x+100=180

2x=80

x=40

measure of other two angle will be 40 degree
