X = 2 for the first one by cross multiplying......sorry about not having time for the other 2
Answer:
The missing angle is 40 degrees
Step-by-step explanation:
Tan = opposite / adjacent
Tan ? = 24 / 29
24 / 29 = 0.8275
Tan-1 of 0.8275 is 39.610
Round to the nearest degree
39.610 = 40
18=-2m+6-m
-6 -6
12=-2m-m
combine like terms
12=-3m
12/-3=m
-4=m
let
x-------> workers in team one initially
y-------> workers in team two initially
we know that
x=2y-----> equation 1
(x-5)=(y-2)+7-----> x-5= y+5----> x=y+10---------> equation 2
equate equation 1 and equation 2
2y=y+10-----> y=10
x=2*10------> x=20
Team 1 now has 20-5 = 15 members Team 2 now hase 10-2 = 8 members
The answer is from 11am to 2pm
hope it helps!
