Answer:
A ≈ 26.6° (nearest tenth)
Step-by-step explanation:
The diagram shows a right triangle. To solve for A, we would apply trigonometric ratio formula.
Reference angle = <A
Opposite = 6 m
Adjacent = 12 m
Apply TOA
Tan A = Opp/Adj
Substitute
Tan A = 6/12
Tan A = 0.5
A = 
A ≈ 26.6° (nearest tenth)
1 answer
weight of karen = k
weight of john = j
by the question
j=3k
then
case II
2j +k =875
2×3k+k=875
7k = 875
k=875/7
k=125
now
j=3k
=3×125
=375
hence john was 375 pound and karen was 125.
2 answer
let Mary be m and joes be j
by question
M=3J
CASE II
M + J=24
3J +J =24
J =24/4
J=6
NOW
M=3×6
M=18
Therefore Mary was 18 yrs old and Joes was 6 yrs old.
He ran 1 meter in about .10 seconds
Hope this helps!
