Please see the attached picture to see the similar triangle.
The new triangle has triple the side lengths of the first one. This means all side lengths will be triple.
You will use this ratio to find the new side lengths and then use them to find the perimeter and area.
3:4:5 = 9 cm: 12 cm:15 cm on triangleABC
1. The
perimeter is 9cm + 12 cm + 15 cm or
36 cm.
2. The
area is 1/2 x 12 x 9 or
54 square cm.
3. The length of the
hypotenuse is
15 cm.
Answer:
b I believe good luck with the answer
Answer:
Step-by-step explanation:
1) 5 - [-5] = 5 + 5 = 10
2)8 - 13 = 8 + (-13) = -5
3) 12 +(-3) = 9
4) x + (-7) = 5
x - 7 = 5
x = 5 + 7
x = 12
We need to add 12 to (-7) to get 5
5) 7 - x = -5
7 = -5 +x
7 + 5 = x
12 = x
We need to take away 12 to 7 to get (-5)
6) 7 - (-10) = 7 + 10 = 17

Its maybe Find the area of the shaded portion sorry it’s wrong I tried my best
Answer:
x = 2
Step-by-step explanation:
If a line is parallel to a side of a triangle and it intersects the other 2 sides then it divides those sides proportionally, that is
=
=
= 2 ( multiply both sides by x + 5 )
6x + 2 = 2(x + 5)
6x + 2 = 2x + 10 ( subtract 2x from both sides )
4x + 2 = 10 ( subtract 2 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2
