Answer:

A = 125º

Step-by-step explanation:

Missing angle is the supplement of 157.5

180 - 157.5 = 22.5

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

Sum of angles in triangle is 180

22.5 + (-10x) + (-x + 20) = 180

Combine like terms

-11x + 42.5 = 180

Subtract 42.5 from both sides

-11x = 137.5

Divide both sides by -11

x = -12.5

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

A = -10(-12.5)

A = 125º

Answer:

For the sum of the digits of Michelle’s father to drop to 1/3 of its’ former value, the second digit must go from 9 to 0, in one year.

Thus, if he is 39 this year, the sum of the digits of his age will be 12. Next year, when the sum of the digits would be 4+0, or 4, then the digits of his age would be 1/3rd of their former value.

Therefore, he is 39, and will be 40 next year

Answer: 33 students wore blue jeans .

Step-by-step explanation:

Let x be the number of black pants.

Given : For the choir concert, the choir director has asked that everyone wear either black pants or blue jeans.

Three times as many students wore black pants as blue jeans.

i.e. Number of blue pants = 4x

If there are forty-four students in the choir, then we have

$x+3x=44\\\\\Rightarrow\ 4x=44$

Divide both sides by 4 , we get

$x=11$

Thus , the number of black pants = 11

Then , the number of blue pants = $3\times11=33$

Therefore, 33 students wore blue jeans .
