Answer:
it is 4/3
Step-by-step explanation:
because tan(B) = opposite/adjacent
Let x = the length of the triangle's hypotenuse
using proportions, this is what the equation looks like:
cross multiply to get:
divide both sides by 45 to get
x=12
Answer: What is the quastion dont under satand.
Step-by-step explanation:
Answer:
44
Step-by-step explanation:
Given, 3x^2 + 3y^2 = 42
=>3(x^2 + y^2) = 42 =>x^2 + y^2 = 42/3= 14
Thus,
= (x - y)^2
= x^2 + y^2 - 2xy
= (x^2 + y^2) - 2xy
= 14 - 2(-15)
= 14 + 30
= 44
