Is first one is 0 and second one is -32/7
Answer:
?=84
Step-by-step explanation:
From the diagram;
![x+120\degree=180\degree](https://tex.z-dn.net/?f=x%2B120%5Cdegree%3D180%5Cdegree)
![x=180\degree-120\degree](https://tex.z-dn.net/?f=x%3D180%5Cdegree-120%5Cdegree)
![x=60\degree](https://tex.z-dn.net/?f=x%3D60%5Cdegree)
Also the interior angles of a triangle adds up to 180 degree.
x+y+90=180
60+y+90=180
y==180-150
y=30
Also, we use angles on a straight line to get;
z+114=180
z=180-114
z=66
Again using sum of interior angles of a triangle, we get;
z+y+?=180
66+30+?=180
96+?=180
?=180-96
?=84
Answer:
y= 4x -15
Step-by-step explanation:
Please see attached picture for full solution.
<u>Given</u>:
Two cylinders are similar. The volume of one is 64 cm³ and the volume of the other is 729 cm³.
We need to determine the scale factor between them.
<u>Scale factor:</u>
Since, it is given that the volume of two cylinders, we need to take cube root.
Thus, we have;
![Scale \ factor=64:729](https://tex.z-dn.net/?f=Scale%20%5C%20%20factor%3D64%3A729)
Taking cube root, we get;
![Scale \ factor=\sqrt[3]{64} :\sqrt[3]{729}](https://tex.z-dn.net/?f=Scale%20%5C%20%20factor%3D%5Csqrt%5B3%5D%7B64%7D%20%3A%5Csqrt%5B3%5D%7B729%7D)
Simplifying, we have;
![Scale \ factor=4:9](https://tex.z-dn.net/?f=Scale%20%5C%20%20factor%3D4%3A9)
Thus, the scale factor between the two cylinders is 4 : 9
