Answer:
AB = 20 tan55°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan55° =
=
=
( multiply both sides by 20 )
20 tan55° = AB
Answer: A
Step-by-step explanation: because the number line shows a gain of 25 then a loss of 25, it represents the question showing +25 then -25. so the answer is A
Hope this helps
Answer:
1. (4)x + y =50
2x + 4y =172
2. (1)x + y =8
150x + 50y =800
3. (1)x + y =20
25 + 10y =290
Step-by-step explanation:
Just trust me and its too much work explaining and im lazy so just ask your teacher or a friend if you can.
The second one is correct
Sinx=1/2
sin30=1/2
therefore x=30 degree
