How many expressions can you find using and that have a value of 12 a=6 b=4 c=-2
1 answer:
Answer:
Step-by-step explanation:
Some of the expressions that can be derived that have the values of 12 are:
i. 2a = 2 x 6
= 12
ii. 3b = 3 x 4
= 12
iii. (b + c) x a = (4 - 2) x 6
= 2 x 6
= 12
iv. 2b + = (2 x 4) + (-2 x -2)
= 8 + 4
= 12
v. -
= (4 x 4) - (-2 x -2)
= 16 - 4
= 12
vi. - b = (-2 x -2 x -2 x -2) + 4
= 16 - 4
= 12

Answer:
407.22 foot is the boat from the base of the lighthouse
Step-by-step explanation:
Given the statement: An observer on top of a 50-foot tall lighthouse sees a boat at a 7° angle of depression.
Let x foot be the distance of the object(boat) from the base of the lighthouse
Angle of depression =
[Alternate angle]
In triangle CAB:
To find AB = x foot.
Using tangent ratio:
Here, BC = 50 foot and
then;
or
Simplify:
AB = x = 407.217321 foot
Therefore, the boat from the base of the light house is, 407.22'
