Answer:
(4, 5 )
Step-by-step explanation:
Given the 2 equations
y = x + 1 → (1)
x + 2y = 14 → (2)
Substitute y = x + 1 into (2)
x + 2(x + 1) = 14 ← distribute and simplify left side
x + 2x + 2 = 14
3x + 2 = 14 ( subtract 2 from both sides )
3x = 12 ( divide both sides by 3 )
x = 4
Substitute x = 4 into (1) for corresponding value of y
y = 4 + 1 = 5
Solution is (4, 5 )
First, we are going to use the Pythagorean identity:

to rewrite our expression. Solving for

in our Pythagorean identity we get that

, so we can rewrite our expression as follows:

Next, we are going to use the trig identity:

to completely simplify our expression:

We can conclude that
