Q. 2)Perimeter =2(l+b)

So,

2(8x-8 +8x)=80cm(Given in Question)

= 2*16x-8=80cm

16x- 8= 80 divided by 2,

16x=40+8=48

x=48 divided by 16

X=3

Q.1) Perimeter=2(l+b)

2(2x+8 +4x)=76cm(Given in Question)

2* 6x +8=76

6x+8= 76 divided by 2, 38

6x= 38-8, 30

x= 30 divided by 6 = 5

X=5

THANK ME LATER

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

tube or goog would be a great resource to with that question
