-25+-50=-75
because they lost 50 points that makes the 50 negative.
Answer:
59 degrees
Step-by-step explanation:
In the figure below, XZ is a diameter of circle A.
Since the Angles (5w+4) and (11w) forms a straight line, then:
![(5w+4)^\circ+(11w)^\circ=180^\circ\\5w+11w+4=180\\16w=180-4\\16w=176\\w=\frac{176}{16}\\ w=11](https://tex.z-dn.net/?f=%285w%2B4%29%5E%5Ccirc%2B%2811w%29%5E%5Ccirc%3D180%5E%5Ccirc%5C%5C5w%2B11w%2B4%3D180%5C%5C16w%3D180-4%5C%5C16w%3D176%5C%5Cw%3D%5Cfrac%7B176%7D%7B16%7D%5C%5C%20w%3D11)
Therefore, the arc measure of YZ will be:
![5w+4=5*11+4=59^\circ](https://tex.z-dn.net/?f=5w%2B4%3D5%2A11%2B4%3D59%5E%5Ccirc)
the value of 25% marked up on $6.75
Answer:
that formula is known as the Pythagorean theorem
