L=3w-4

Perimeter = 64

64=2L+2w

Plug in L that we solved above into this equation:

64=2(3w-4)+2w

64=6w-8+2w

64=8w-8

72=8w

w=9

Plug W back into the equation above to solve for L

L=3w-4

L=(3)(9)-4

L=23

Check the answer with the perimeter formula:

P=2L+2w

P=2(23)+2(9)

P=46+18

P=64

If in a triangle ABC, a-25, b=16, c=9 then tan(A/2) is?
Fiesta28 [93]
We have the following givens:
a=25 
b=16
c=9
We can make use of the Laws of Cosines in solving the angle A such as:
cos A = (b²+c²-a²)/2bc
cos A =((16)²+9²-(25)²)/1*16*9
A=180°

tan (A/2)=tan(180/2)

Anybody Know This. ?
Pepsi [2]

Answer:

<em>B.) ABC is similar to DEF because 6/4 = 12/8 = 9/6!</em>

Step-by-step explanation:

ABC is similar to DEF because the ratio of there sides are the same! If two triangles have three pairs of sides in the same ratio, then the triangles are similar.

6 \div 4 = 1.5\\12 \div 8 = 1.5\\ 9 \div 6 = 1.5

The ratio stays 1.5 in all instances! These tringles are similar.
