when running a line, in a right-triangle, from the 90° angle perpendicular to its opposite side, we will end up with three similar triangles, one Small, one Medium and a containing Large one, from where we can use proportions to get their sides, so Check the picture below.
Answer:
48
Step-by-step explanation:
Answer:
163.75
Step-by-step explanation:
a scale factor applies normally to lengths (one-dimensional sizes).
and the perimeter is calculated just by lengths (the side lengths).
so, we can apply the scaling factor directly to the perimeter.
perimeter of DEF = 5/2 × perimeter of ABC = 5/2 × 65.5 =
= 163.75 ft
what was step 1 ? we did not need it ?
Answer:
x-10=2y+3
Step-by-step explanation:
Ten less than a number <em>x</em> is equal to three more than two times a number <em>y</em>
<em />
D=(S+8)/C
S=DC-8
add 8 to both sides
S+8=DC
divide c from both sides
(S+8)/C=D
