In geometry,
A point represents a point
Two points define a line extended on both sides of the points.
Two points define a ray if it extends on only one side of either of the points.
Three or more than three points define a plane.
Now as far as a wall is considered, it is a flat surface on which we can plot infinite points.
Hence the wall represents a plane.
Option C) is the right answer.
Hi there! In this problem, you should have the knowledge of three basic Trigonometric Ratio.
- sinA = opposite/hypotenuse
- cosA = adjacent/hypotenuse
- tanA = opposite/adjacent
Now that we know three basic ratio. Let's check each choices!
This choice is wrong because we focus on the 50° angle. When we focus on 50°, sin50° should be d/x and not d/c.
This choice is also wrong because in ratio, it's cos50° that adjacent/hypotenuse.
This choice is correct! As ratio states, tanA = opposite/adjacent.
This choice is wrong. x/c is a reciprocal of cosine which is 1/cos. We call the reciprocal of cosine as secant or sec in short.
This choice is wrong as x/d is a reciprocal of sine which is 1/sin. We call the reciprocal of sine as cosecant or cosec/csc in short.
This choice is right by the ratio. Nothing really much to explain since we follow by ratio that is defined.
Answer
Questions can be asked through comment.
Furthermore, tan also has its reciprocal form itself which is called cotangent also known as cot in short.
Hope this helps, and Happy Learning! :)
About $0.37 because you divide $4.49 by 12
Sorry I’m just commenting to do it
Answer:
y = 6
Step-by-step explanation:
You just multiply the 3 and the 2 which equals 6
