1. product of 23 and f
2. seven cubed
3. five multiplied by m squared then plus two
4. four multiplied by d cubed them minus ten
5. 10 - U or U - 10
6. 18 + X
7. 33j
8. 74 + 3y
we know that
if ∠UVW and ∠XYZ are complementary angles
then
∠UVW + ∠XYZ=90°
∠UVW=x-10
∠XYZ=4x-10
substitute the values
(x-10)°+(4x-10)°=90°
Solve for x
5x-20=90
5x=90+20
5x=110
x=22°
∠UVW=x-10=22-10=12°
∠XYZ=4x-10=4*22-10=78°
therefore
<u>the answer is</u>
x=22°
∠UVW=12°
∠XYZ=78°
The approximate margin of error is 4%.
Using the formula given and our information, we have:
300\250
1.2
or
6\5
I hope this help
