Answer:
<h2>
Angle X; 39</h2><h2>
Angle Y; 129</h2>
Step-by-step explanation:
180-90
90
This gives us the measurement of 51+x.
90-51
39
This is x as well as the angle that is across from it.
x+90=y
39+90=129
y=129.
to find the last angle, we add 90 to 51. This gives us 141.
So, now we add up all of the angles to double check everything. If they all add up to 360 then we are correct.
39+39+51+90+141=
360.
This means that we have solved everything correctly and that these are the correct answers.

Answer:
(a). $20,000
(b). The estimate will be lower than the actual amount.
Step-by-step explanation:
We have been given that Michael saves $423 dollars a month for college.
(a). We know that 1 year equals 12 months.
4 years = 4*12 months = 48 months.

Since we are asked to find the estimated amount of money Michael will save in 4 years, so we will estimate both quantities as:



Therefore, Michael will save approximately $20,000 in 4 years.
(b).
The estimate will be lower than the actual amount as we rounded $423 down $23 to nearest hundred that is $400 and rounded 48 up 2 to nearest ten that is 40.
Therefore, the estimate will be lower than the actual amount.
