Answer:
8.1
Step-by-step explanation:
Since we dealing with right triangles, we are going to use pythagoern theorem.
+
=
, where a and b are the two legs and c is the longest side or the slanted side( known as hypotunese.)
Let plug in the numbers
4^2+ b^2=9^2
16+b^2=81
b^2=65
sqr root of 65 is about 8.1
15.66 is what I got in my calculator if you turn %65 into .65
I hope this helps you
((7+8)+8).8/2
(15+8).4
23.4
92
A.
A-triangle may have only one right or only one obtuse, may have two or three acute angles but never just one
because a triangle has three angles the m= 180, the other twp angles have to be acute
Hope this helps
