The answer to your question is option d as x is positive ( making it open up), and the vertex is (-3,-4)
Answer:
Step-by-step explanation:
<u>Properties of a parallelogram</u>
- Two adjacent angles are supplementary
- Opposite angles are congruent
- Opposite sides are parallel and congruent
Use the properties to find the required parameters
1) <u>Find m∠YXV</u>
- m∠YXV + m∠VXW + m∠VWX = 180°
- m∠YXV + 40° + 84° = 180°
- m∠YXV = 180° - 124°
- m∠YXV = 56°
2) <u>Find m∠Y</u>
3) <u>Find x</u>
No, because
60/3 = 20
90/6= 15
Both of the answers aren’t equivalent.
Answer:
x = 97.6
Step-by-step explanation:
cos = adjacent over hypotenuse
![cos(55)=\frac{56}{x}](https://tex.z-dn.net/?f=cos%2855%29%3D%5Cfrac%7B56%7D%7Bx%7D)
* multiply each side by x *
![cos(55)*x=xcos(55)\\\frac{56}{x} *x=56\\56=xcos(55)](https://tex.z-dn.net/?f=cos%2855%29%2Ax%3Dxcos%2855%29%5C%5C%5Cfrac%7B56%7D%7Bx%7D%20%2Ax%3D56%5C%5C56%3Dxcos%2855%29)
* divide each side by cos ( 55 ) *
![\frac{xcos(55)}{cos(55)} =x\\\frac{56}{cos(55)} =97.63302055](https://tex.z-dn.net/?f=%5Cfrac%7Bxcos%2855%29%7D%7Bcos%2855%29%7D%20%3Dx%5C%5C%5Cfrac%7B56%7D%7Bcos%2855%29%7D%20%3D97.63302055)
we're left with x = 97.63302055
Our last step is to round to the nearest tenth of a foot
We get that x = 97.6
