Answer:
28 m
Step-by-step explanation:
The top angle in the triangle = 90° - 62° = 28°
Using the cosine ratio in the right triangle
cos28° =
= 
cross- multiply
x × cos28° = 25 ( divide both sides by cos28° )
x =
= 28.31425... ≈ 28 m
Thus the distance from the top to the crocodile is 28 m
Answer:
28.31 m to the nearest cm.
Step-by-step explanation:
Note the angle next to the crocodile measures 62 degrees ( alternate angles).
The required distance is the hypotenuse of the triangle and the height 25m is the opposite side to the angle of 62 degrees..
Therefore we have sin 62 = 25 /x where x is the distance required.
x = 25 / sin 62
= 28.31 m.

Answer: C
Step-by-step explanation:
4x + 1 = 9
4x + 1 -1 = 9-1
4x=8
8/4=2
Answer:
8
Step-by-step explanation:
Well 2x=16 is the same as x=8 when you divide by 2. So the dot should be on 8.
9 <= 17 -4x
Subtract t 17 from both sides:
-8 <= -4x
Divide both sides by-4,
2 <= x
Rewrite the inequality with the x on the left side.
Answer: x <=2
Answer:
Just took the test the answer is -9!
