The new figure is formed differently and is not the same as the other ome
<h2>Answer:</h2>
12 + 6
Add Them:
12 + 6 = <u>18</u>
7 + 7 + 12
Add Them:
7 + 7 + 12 = <u>2</u><u>6</u>
Begin with cos(θ) = 5/13, θ in Quadrant IV
you should distinguish the 5-12-13 right-angled triangle
and then cosØ = adjacent/hypotenuse
x = 5, r = 13 , y = -12, since Ø is in IV
and sinØ = -12/13
also tan(ϕ) = −√15 = -√15/1 = y/x and ϕ is in II,
y = √15 , x = -1
r^2 = x^2 + y^2 = 15+1 = 16
r = 4
sinϕ = √15/4 , cosϕ = -1/4
you must know that:
cos(θ − ϕ) = cosθcosϕ + sinθsinϕ
= (5/13)(-1/4) + (-12/13)(√15/4)
= -5/52 - 12√15/52
= (-5-12√15)/52
Answer: Answer is in the steps
Step-by-step explanation:
The interior angles of a triangle add up to one 180 degrees so they all have to add up to 180 degrees.
A) (x+10)° + 50° + (x+20)° = 180°
B) Now solve for x using the equation
x+10 + 50 +x+20= 180
2x + 80 = 180
-80 -80
2x = 100
x = 50
