Step-by-step explanation:
they have to be equivalent
The answer is on the paper
Answer:
see explanation
Step-by-step explanation:
The opposite angles of an inscribed quadrilateral are supplementary, thus
5x + 20 + 7x - 8 = 180
12x + 12 = 180 ( subtract 12 from both sides )
12x = 168 ( divide both sides by 12 )
x = 14
Thus
∠ RQP = 10x = 10(14) = 140°
∠PSR = 180° - 140° = 40° ( opposite angles are supplementary )
∠ SRQ = 7X - 8 = 7(14) - 8 = 98 - 8 = 90°
∠ QPS = 5x + 20 = 5(14) + 20 = 70 + 20 = 90°
Answer:
Step-by-step explanation:
Apply rule : ![a^\frac{1}{3}=\sqrt[3]{a}](https://tex.z-dn.net/?f=a%5E%5Cfrac%7B1%7D%7B3%7D%3D%5Csqrt%5B3%5D%7Ba%7D)
![8^\frac{1}{3}=\sqrt[3]{8}](https://tex.z-dn.net/?f=8%5E%5Cfrac%7B1%7D%7B3%7D%3D%5Csqrt%5B3%5D%7B8%7D)
8 is a perfect cube. Evaluate the cube root of 8.
![\sqrt[3]{8}=2](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8%7D%3D2)
Answer:
Step-by-step explanation:
(x₁, y₁) = (-9, 7) & (x₂ , y₂) = (9 , -3)
Slope = 
![= \frac{-3-7}{9-[-9]}\\\\= \frac{-3-7}{9+9}\\\\=\frac{-10}{18}\\\\= \frac{-5}{9}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B-3-7%7D%7B9-%5B-9%5D%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B-3-7%7D%7B9%2B9%7D%5C%5C%5C%5C%3D%5Cfrac%7B-10%7D%7B18%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B-5%7D%7B9%7D)
