B, because
3/15=x/75
75/15=5
3*5=15
15 is your answer.
I'm guessing you find the length of the hypotenuse using the pythagorean theorem.
a² + b² = c² a and b are the legs and c is the hypotenuse
15² + 8² = c²
225 + 64 = c²
289 = c²
√289 = √c²
17 = c
hope that helps, God bless!
The first one because of you add 10 and 4 you get 14. And they both multiply 6 by 14.
Answer:


Step-by-step explanation:
Required
Find m and n
Considering the given angle, we have:

This gives:

Make m ths subject


So, we have:


Considering the given angle again, we have:

This gives:

Make n the subject


So, we have:


M^2 - 2mn + n^2
(-2)^2 -2(-2)(4) + 4^2
4 + 16 + 16
36
