Answer:
49 units
Step-by-step explanation:
Given the triangles are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
22BC = 484 ( divide both sides by 22 )
BC = 22
------------------------------------------------
Similarly
=
, substitute values
=
( cross- multiply )
22AC = 352 ( divide both sides by 22 )
AC = 16
Thus perimeter of Δ ABC is
perimeter = AB + BC + AC = 11 + 22 + 16 = 49 units
Answer:
25 in; C
Step-by-step explanation:
Hey!
There probably is a reason she is deleting. You could contact her or ask some help elsewhere.
Anyway! I'm trying to get this in fast. (Remember the Pythagorean Theorem?) That will be very useful here since it is a right triangle.
<u>L² + L² = H² (or H² - L² = L²):</u>
In that case, we'll use the second one because our Hypotenuse is given.
We can substitute each value of the numbers:
65² - 60² = L²
Evaluating:
4225 - 3600 = 625
√625 = 25 inches
Thusly, the third side would be
<em>Also note we could have simplified into a Pythagorean Triple. This method is a simpler more basic method for learning the concept.</em>
Hope this helps!
