Answer:
7.8
Step-by-step explanation:
distance formula works like this
(difference in xs)² = difference of 8 and 3 is 5² = 25
and
(difference in ys)² = difference of 2 and 8 is 6² = 36
add them = 61
square root of that = √61 = 7.8
Remember ‘difference’ refers to subtraction, so they are looking for the ‘difference’ of a a number, which is unknown, so we can use the variable ‘x.’ X-7
The term ‘at least’ refers to our greater than, less than, equal to signs
Difference of a number and 7 = x-7
Four times = (4) or •4
At least = <
-52 = Answer negative 52
Plug them all in,
x-7(4)<-52
Answer:
34
Step-by-step explanation:
All angles of a triangle add up to 180 degrees so you would subtract from 180 with the angles you already have to get your answer. 180 - 115 - 31 = B which is 34.
