Center of rhombus bisects 90°.
Sum of angles in triangle = 180°
x + x + 14 + 90 = 180
2x + 104 = 180
2 (x + 52) = 180
x = (180 ÷ 2) - 52
x = 90 - 52
x = 38°
Answer: 
Step-by-step explanation:
The formula for calculate the area of a Sector of a circle is:
Where "C" is the central angle in degrees and "r" is the radius.
Based on the data given in the exercise, you can identify that:
(See the figure attached)
Then, you can substitute these values into the formula and then evaluate, in order to calculate the area of lawn that receives water.
The result is:
The perimeter is 24 but I’m not sure about the area
Answer:
The sigma notation would look like this:
∞
Σ 48(1/4)^i-1
i = 1
Step-by-step explanation:
I can't seem to find a good way to make it more connected so I'll just have to tell you. The ∞ is above the ∑, while the i = 1 is under it. That is all one thing. The rest is followed as normal, and it is all next to the ∑
Answer:
y = 2x - 3
Step-by-step explanation:
The negative recipricol is -1/(-1/2) = 2
Use point-slope equation:
y-y1 = m(x-x1)
x1 = 3, y1=3
y-3 = 2(x-3)
y-3 = 2x-6
<u>y = 2x-3</u>
