Answer:

y over cos 50 degrees

Step-by-step explanation:

GIVEN : A Right Angled Triangle with sides x,y,z with base angle 50°

            BASE = y

            HYPOTENUSE = z

To Find: expression shows the value of z

We will use trigonometric ratios

Since we know

cosine or cosθ = Base/ Hypotenuse (equation 1)

In the given figure we can see hypotenuse is z and base is y and θ = 50°

Putting values in equation 1 we get :

cos 50° = \frac{y}{z}

⇒z = \frac{y}{cos 50}

so z= y over cos50°

Y=-x^2+2x+10<br> y=x+2<br><br> Substitution<br> Need ASAP
aniked [119]

Answer:

x_1=\frac{1+\sqrt{33} }{2},y_1=\frac{5+\sqrt{33} }{2}\\ \\ x_2=\frac{1-\sqrt{33} }{2},y_2=\frac{5-\sqrt{33} }{2}

Explanation:

You must find the solution of the system using the substitution method.

System:

y=-x^2+2x+10\\\\ y=x+2

Substitute x+2 for y:

x+2=y=-x^2+2x+10

Pass all the terms to one side:

x^2-2x+x+2-10\\ \\ x^2-x-8=0

Use the quadratic formula to solve:

x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}\\ \\ x=\frac{-(-1)+/-\sqrt{(-1)^2-4(1)(-8)} }{2(1)}\\ \\ x=\frac{1+/-\sqrt{1+32} }{2}

x_1=\frac{1+\sqrt{33} }{2}\\ \\x_2=\frac{1-\sqrt{33} }{2}

Use y = x  + 2 to find the value of y:

y_1=2+x_1=2+\frac{1+\sqrt{33} }{2}\\ \\y_1=\frac{5+\sqrt{33} }{2} \\\\y_2=2+x_2=2+\frac{1-\sqrt{33} }{2}\\ \\ y_2=\frac{5-\sqrt{33} }{2}

We started our with 10 points. 
He loses 20 points, which brings him down to -10 points. 
In the final round he earned 40 points. 40 minus the negative ten points gives us an answer of 30 points.
