Express 4 less than a number is actually easy.
X will be our number.
But it won't be just X, it would be X squared or x^2.
So you do... (x^2)-4.
(The 4 is what you subtract).

One angle of an isosceles triangle measures 100°. Which other angles could be in that isosceles triangle? Choose all that apply.

Ivenika [448]

Answer:

40 degrees

Step-by-step explanation:

The sum of the angles is 180.

A 100 degree angle cannot be a base angle because then

the sum of the base angles would be 200 degrees.

The 100 must be the vertex angle.

Equation:

x + x + 100 = 180

2x = 80

x = 40 degrees.

Each of the base angles is 40 degrees.
