In the fist you have to know: any angle opposite the head is equal in measurement.
so now we know one angle in the triangle it is 82
All corners of the triangle are equal 180
so we have to do this 180-82=98
so we have to collection (4x+8)+(8x-6)=98
12x+2=98
12x=96
x=8
4(8)+8=40
the answer is 40

1.Your primary job’s gross income is $3,500.00/month, and your second job’s realized income is $368.49/month. Deductions are FIC

bazaltina [42]

Part 1
Total income per month = $3,500+$368.49 = $3,868.49
Total deductions = 7.65%+10.75%+8.35% = 26.75% = 0.2675

Net income = Total income - Deductions = Total deductions (1-0.2675) = $3,868.49 (1-0.2675) = $2,833.67

Part 2
Fixed expenses = $1,035.65 which is 36% of realized income.

Then, if realized income is 100%;
$1,035.65 ------------------ 36%
$ Realized income ----- 100%
Therefore,
Realized income = 1,035.65*100/36 = $2,876.81
