Answer:
complementary
Step-by-step explanation:
The total angle is a right angle. Complementary angles are angles that add up to 90 degrees. Right angles are 90 degrees so the answer is complementary.
Step-by-step explanation:
Set M = {20,22,24,26,28,30,32,34}
n(M) = no. of elements in set M
i.e.
n(M) = 8
Answer:
The answer is image 3.
Step-by-step explanation:
The equation for the line will be y = (-1/2)x + 3 so the gradient is negative and you will have to find the x-intercept and y-intercept.
x-intercept :
![let \: y = 0](https://tex.z-dn.net/?f=let%20%5C%3A%20y%20%3D%200)
![0 = - \frac{1}{2} x + 3](https://tex.z-dn.net/?f=0%20%3D%20%20%20-%20%5Cfrac%7B1%7D%7B2%7D%20x%20%2B%203)
![\frac{1}{2} x = 3](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20x%20%3D%203)
![x = 3 \div \frac{1}{2}](https://tex.z-dn.net/?f=x%20%3D%203%20%5Cdiv%20%20%5Cfrac%7B1%7D%7B2%7D%20)
![x = 6](https://tex.z-dn.net/?f=x%20%3D%206)
y-intercept :
![let \: x = 0](https://tex.z-dn.net/?f=let%20%5C%3A%20x%20%3D%200)
![y = - \frac{1}{2} (0) + 3](https://tex.z-dn.net/?f=y%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20%280%29%20%2B%203)
![y = 3](https://tex.z-dn.net/?f=y%20%3D%203)
