Answer:

x = 82.5

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

x + x - 45 + 60 = 180, that is

2x + 15 = 180 ( subtract 15 from both sides )

2x = 165 ( divide both sides by 2 )

x = 82.5

Answer:

--------------------------------------------------

Step-by-step explanation:

60+x-45+x=180

60-45+2x=180

15+2x=180

2x=180-15

2x=165

x=165/2

x=82.5

Please help answer the following question
Elena L [17]

Answer:

D

Step-by-step explanation:

The unmarked angle of the triangle is also 40o. The triangle is marked with two equal sides (isosceles).

<2 + 40 + 40 = 180            Combine the left

<2 + 80 = 180                    Subtract 80 from both sides

<2 = 180 - 80

<2 = 100 degrees.

That's not the answer. We have to solve for x

<2 = x + 106

100 = x + 106       Subtract 106 from both sides

100 - 106 = x

x = - 6

tiny-mole [99]

Answer:

\frac{3}{10}

Step-by-step explanation:

In probability, "AND" means "multiplication" and

"OR" means "addition".

We want the probability that she picks FAVORITE SHIRT "AND" FAVORITE PANT.

Probability that she picks favorite shirt = 3/5

Probability that she picks favorite pants = 2/4 = 1/2

Since, "AND", we "multiply" both to get:

3/5 * 1/2 = 3/10
