Answer:
180
Step-by-step explanation:
Area of troiangle=180
A+B+C=180
22+90+B=90
112+B=180
B=180-112
B=68
perimeter=A+B+C
22+90+68=180
Answer:
width=18cm
Step-by-step explanation:
perimeter= 2(l+b)
90=2(27+b)
90/2=27+b
45-27=b
b=18cm
Let's solve for x.
5x+15y=12
Step 1: Add -15y to both sides.
5x+15y+−15y=12+−15y
5x=−15y+12
Step 2: Divide both sides by 5.
5x
5
=
−15y+12

Answer:
x=−3y+12/5
Let's solve for y.
5x+15y=12
Step 1: Add -5x to both sides.
5x+15y+−5x=12+−5x
15y=−5x+12
Step 2: Divide both sides by 15.
15y
15
=
−5x+12

X = 360 - (122+58+58)
x = 360 - 238
x = 122
