L=w+2 and 2w+2l=44
substitute equation for length in perimeter equation
2w+2(w+2)=44
2w+2w+4=44
4w+4=44
4w=40
w=10
substitute width into length equation to get length
l=10+2
l=12
a=lw
a=12*10
a=120 cm^2
Answer:
x = 10°
Step-by-step explanation:
If Angles 1 and 2 are complementary, then:
Angle 1 + Angle 2 = 90°
Since Angle 2 = 65°, Angle 1 + 65° = 90° → 3x - 5 + 65° = 90°, or
3x + 60° = 90°
Then 3x = 30, and x = 10
