Step-by-step explanation:

Isosceles Triangles

The base angles of an isosceles triangle are those formed by the base and one leg of the triangle.

On the other side, the base angles theorem converse states if two angles in a triangle are congruent, then the sides opposite those angles are also congruent.

We are given an isosceles triangle with base angles 3x-11 and 2x+11. Applying the theorem as explained above:

3x - 11 = 2x + 11

Subtracting 2x:

x - 11 = 11

Adding 11:

x = 22

The base angles have a measure of

3x - 11 = 3*22 - 11 = 55°

Thus, the remaining angle of the triangle is:

y = 180° - 2*55° = 180° - 110° = 70°

x = 22°, y = 70°

A bag contains 6 red marbles, 2 white marbles, and 1 gray marble.You randomly pick out a marble,record its color,and put it back

Dominik [7]

You should expect 5. There is one grey marble out of 9 total, and that can be expressed as 1/9. Since you repeat it 45 times, it's 1/9 45 times, or 1/9(45).

$\frac{1}{9} * \frac{45}{1}$

1*45 is 45

9*1 is 9.

45/9 is 5.
