Answer:
x = 76.9
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp side / adj side
tan 70 = x/28
28 tan 70 = x
x=76.92936
Rounding to the nearest tenth
x = 76.9
Answer:
320 meters
Step-by-step explanation:
x² + 200x = 166400
It's a square, area should be side²
x² + 2(x)(100) = 166400
x² + 2(x)(100) + 100² = 166400 + 100²
(x + 100)² = 176400
x + 100 = 420
Since these are sides, we just consider the positive square root
x + 100 = 420
x = 320m
(10x5)+(10x14)+(10x-3)
50+140-30
160
Answer:
You are correct 3(8n-8) and 24n-24 is the right answer
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
So the midpoint of AB can be calculated by finding the length of AB, dividing it by 2 and then adding it to A. So the length of AB is equal to B-A or in general the difference between two values is |a-b| where the order doesn't matter, but assuming B is the right side (meaning it should be greater than A) the length should be B-A. in this case A = -5 and B = 3 so the length is 3 - (-5) = 8. The length is 8 so the midpoint is half of that which is 4, now adding 4 to the left side (A) you get -5 + 4 = -1. So the midpoint of AB lies at -1. Now the midpoint of AC can be found using the same process. 7 - (-5) = 12 => 12/2 = 6 => -5 + 6 = 1 so the midpoint of AC is at 1. Now to find how many units from the midpoint AB to AC you just subtract the midpoint of AB from AC. this gives you 1 - (-1) which is 2.
