Answer:
Graph B represents a function.
Step-by-step explanation:
Graph B is a quadratic function. y = x^2
Check the picture below.
well, since the triangle is an isosceles, with twin sides and twin angles at the "base", let's check what the angle at R is, 15(7) - 31 = 74, and her twin sister at T is also 74, that means that the angle at S is 180 - 74 - 74 = 32.
Answer:
Both of the angles will add up to 180 degrees so let’s make an equation.
5x-5+2x+10=180
First we collect like terms
5x+2x-5+10=180
Add them up
7x+5=180
Move the constant to the right
7x=180-5
7x=175
7x/7=175/7
x=25
So yes it’s true x=25.
Now we find the respective angles,
5x-5
5(25)-5
125-5
120
So angle one is 120 degrees.
2x+10
2(25)+10
50+10
60
So angle two is 60 degrees.
Now to check,
120+60=180

We can use SOH, CAH and TOA, but first we must find the length of a hypotenuse:
h =

sin (theta)=
2/√13cos ( theta) =
-3/√13tan (theta) =
-2/3cot (theta ) =
-3/2sec (theta) = 1/cos(theta ) =
-√13/3csc(theta ) = 1/ sin (theta) =
√13/2
