Answer:

A. 17°

Step-by-step explanation:

We know that point r is 73° and point p is a right angle (90°) all triangles equal 180° on the inside. If you add 73 and 90, you get 163. Then subtract 163 from 180 to get 17.

What are the zeros of the quadratic function?<br> y = x^2 - 2x - 15
Pie

Answer:

x=\frac{1+\sqrt{31}}{2},\:x=\frac{1-\sqrt{31}}{2}

Step-by-step explanation:

-> 0=2x^2-2x-15

-zeros means the solution aka x intercept, meaning y=0

x_{1,\:2}=\frac{-\left(-2\right)\pm \sqrt{\left(-2\right)^2-4\cdot \:2\left(-15\right)}}{2\cdot \:2}

=> according to quadratic formula

x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

where ax^2+bx+c=0

=> x_{1,\:2}=\frac{-\left(-2\right)\pm \:2\sqrt{31}}{2\cdot \:2}

simplify

x_1=\frac{-\left(-2\right)+2\sqrt{31}}{2\cdot \:2},\:x_2=\frac{-\left(-2\right)-2\sqrt{31}}{2\cdot \:2}

x=\frac{1+\sqrt{31}}{2},\:x=\frac{1-\sqrt{31}}{2}

Cannot simplify farther
