What is the exact distance between point e and point f

The answer to your question is: d = √73  

Step-by-step explanation:

data

Point E (-3, 4)

Point F (5, 1)

Formula

d = √((x2-x1)² + (y2-y1)²)

d = √(5-(-3))² + (1-4)²)          substitution

d= √ (5+3)² + (-3)²               simplify

d= √ 8² + -3²

d = √ 64 + 9

d = √73                               result

line or a linear equation graph

step-by-step explanation:

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
