Answer:
yes
Step-by-step explanation:
Yes this triangle is right angled and can be justified using the Pythagorean theorem. The theorem states that: 
. Substitute using the given values:
(9^2)+(12^2)=15^2
81 + 144 = 255
255 = 255.
It satisfies the theorem therefore it is a right angle triangle.
the 3rd one. hope this helps
At least 8 routes, at most 63 routes
12m-32=-80
12m=-80+32
12m=-48
m=-4
If we are given a triangle JKL and we assume that this is a right triangle, we can find the measure of the angle LJK by using formulas derived from the Pythagorean Theorem.If opposite side = 10 hypotenuse = 15then, we can use: cos (x) = opposite / hypotenusesin (x) = 10 / 15
