Answer:
y = 45°
Step-by-step explanation:
4 sides = 360°
(2y+1)° + y° + 112° + 112° = 360°
2y + y = 360 - 112 - 112 - 1
3y = 135
y = 135÷3
= 45°
They are the same length,because 3 fr is the same as 12 inches times 3 equals 36 inches
Mark earns 33.5 dollars per hour.
Use this equation to solve the problem:
x - (x * .25) = 40
This equation is saying the original price times itself by 25% is 40.
x - (x * .25) = 40
Simplify.
x - .25x = 40
.75x = 40
Divide both sides by .75.
x = 53.33
The original price was $53.33
R = 4 x + 8y [ Given ]
when ,
x = 4 and R = 32
★ Substituting the values
=> 32 = 4 × 4 + 8y
=> 32 = 16 + 8y
=> 8y = 32 - 16
=> 8y = 16
=> y = 8/16
=> y = 2
