(1, 2), (2, -3), (3, 4), (4, -5)
Step-by-step explanation:
Answer:
b = 15°
Step-by-step explanation:
The base angles (c = ∠QRP) of ΔQPR are such that the sum of angles of the triangle is 180°. Since the triangle isosceles, the base angles are equal:
2c +60 = 180
2c = 120
c = 60 . . . . . . degrees; the base angle of ΔQPR
__
Likewise, the base angle (∠SRP) of ΔSPR is ...
a = (180 -90)/2 = 45 . . . . . degrees
__
The measure of angle b is the difference between the larger and smaller base angles:
b = c -a = 60° -45°
b = 15°
D, because 3 and 9 go into some odd numbers. 2 is your answer
Answer: 3 Multiply
Step-by-step explanation: u would Multiply 4x7
s = number of slices for a large pizza
so if "s" is the number of slices in 1 large pizza, the total for 1 pizza will just be 1s, for two pizzas will be 2s and so on, so for 4 pizzas the total will just be 4s.
we also know there were an extra 3 slices, and we also know that whatever 4s is plus 3 will give us the total of 51 slices of pizza.
![4s + 3 = 51\implies 4s = 48\implies s = \cfrac{48}{4}\implies \boxed{s = 12}](https://tex.z-dn.net/?f=4s%20%2B%203%20%3D%2051%5Cimplies%204s%20%3D%2048%5Cimplies%20s%20%3D%20%5Ccfrac%7B48%7D%7B4%7D%5Cimplies%20%5Cboxed%7Bs%20%3D%2012%7D)
