Answer: 17
if A+B= 5 and a-b=3, then a=4 and b=1. So, 4^(2)+1^(2)= 16+1=17
Answer:
Approximately 7.8 units
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula:
From the graph, we can see that A is (0,0). Let's let this be x₁ and y₁.
B is (-5,6). Let's let this be x₂ and y₂. So, substitute:
Simplify:
Square:
Add:
Take the square root. Use a calculator:
So, the distance between them is about 7.8 units.
And we're done!
In a circle, the measure of an inscribed angle is half the measure of the intercepted arc ⇒ AC = 75·2 = 150°
Depends on the formula, but with most cases yes, because you may have -3 as an answer, but adding only 4 makes it positive.
There are some cases where you could look at it and know the sign, like if I am adding -100 and -93, I know the answer will be negative
