Answer:
triangle goes brrrrrmmm
Step-by-step explanation:
Well, we know that the legs of this triangle are equal, and we know
that the area of any triangle is (1/2)(base)(height) .
Since this is a right triangle, we can set it down on one leg, and then
the other leg will be the height. Then ...
Area = (1/2) (base) (height)
= (1/2) (leg) (leg)
65 cm² = (1/2) (leg)²
Multiply each side by 2 : 130 cm² = (leg)²
Take the square root of each side: leg = √130 cm² = 11.402 cm
rounded to the nearest tenth: 11.4 cm
Use Pythagoras to get the height, the use it to find x:
26^2-11^2 =555
555^1/2(square root of 555)
=23.55843798 ~you need this number left as it is for a more accurate answer.
Then you do
42^2-23.55...^2(which we know is 555)
Then whatever that equals you square root that
Then you round up the answer to that to get the final answer.
I left the last part so you can do it and do some active learning, if you have more questions on this please feel free to ask, hope this helps
Answer:
9x4=36
Step-by-step explanation:
5/√11 = 5√11/√11√11 = 5√11/11
6/√8 = (2*3)/(2^3/2) = 3√2/2
√(5/7) = √35/7
