Answer:
18.682
Step-by-step explanation:
Given that :
E = (-7, - 2) ; x1 = - 7 ; y1 = - 2
F = (11, 3) ; x2 = 11 ; y2 = 3
EF = √((x2 - x1)² + (y2 - y1)²)
EF = √((11 - -7)² + (3 - -2)²)
EF = √((11 + 7)² + (3 + 2)²)
EF = √(18² + 5²)
EF = √324 + 25
EF = √349
EF = 18.6815
EF = 18.682 units (3 decimal places )
X° = 180° - 160°
= 20°
x = 20
The answer is 27:25 but it’s not on your letters
B) -23 because a double negative is a positive so it’s -35 + 12 which is -23
