Answer:
80°
Step-by-step explanation:
Let the angle be x then four times it's complement plus 60, that is
4(90 - x) + 60 ← is it's supplement
Supplementary angles sum to 180°
Sum the angle and it's supplement and equate to 180
x + 4(90 - x) + 60 = 180 ← distribute and simplify left side
x + 360 - 4x + 60 = 180
- 3x + 420 = 180 ( subtract 420 from both sides )
- 3x = - 240 ( divide both sides by - 3 )
x = 80
The required angle = x = 80°
supplement = 4(90 - 80) + 60 = 4 × 10 + 60 = 40 + 60 = 100°
180=76+4x
180-76=4x
104=4x
104/4=x
26=x
Measurement A= 26
The total purchase price including sales tax will be $1449.6136
<em><u>Explanation</u></em>
Festus bought a computer at $736.34, Apple iPad at $249.99 and a printer at $381.23
So, the <u>total price of all three items</u>
dollar.
The sales tax rate is 6%. So, <u>the amount of sales tax</u>
dollar.
Thus, the total purchase price including sales tax will be: (1367.56 + 82.0536) dollar = 1449.6136 dollar
