The sum of the angles in a triangle is 180, so the equation will be :
2k+k+45= 180
add similar variables
3k+45=180
3k=135 (divide each side by 3)
k= 45
So 2k equals= 90
k=25
This is right angle triangle for your info!
The minimum number of sides that a polygon must have is 3
Its letter b can u please help me in my question
2x² + 5x -6x - 15 = 0
2x² - x - 15 = 0
2x² -x = 15
x = 3
3 x 3 = 9 x 2 = 18 - 3 = 15
i really don't know how i got 3 in the first place but that is your answer
hope this helps
Answer:
A = 201.06 square inches
Step-by-step explanation:
Radius of the pizza is 8 inches.
It is required to find the area of the pizza get by Emily's family.
Pizza is in the shape of circle. Area of a circular figure is given by :
![A=\pi r^2\\\\A=\pi (8)^2\\\\A=201.06\ in^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2%5C%5C%5C%5CA%3D%5Cpi%20%288%29%5E2%5C%5C%5C%5CA%3D201.06%5C%20in%5E2)
So, the Emily's family will get 201.06 square inches of pizza.
