Answer:
im cant help because im learning about this
Step-by-step explanation:
X -3y = -15
Subtract 'x' from each side:
-3y = -x - 15
Divide each side by -3 :
<em>y = 1/3 x + 5</em>
This is 'slope-intercept' form.
The
purple line is tangent. Tangent line intersects a circle in only 1 point
The
yellow dot is the point of tangency. It is the point where tangent line touches the circle
The
light blue line is secant. Secant line intersects a circle in 2 points
The
red line is the radius. Radius is the distance from center to the outer rim of the circle.
The
green line is the diameter. It is the line passing through the center of a circle. It measures twice the radius
The
gray line is the chord. Chord is the line whose endpoints lie on the circle.
Arc AB is a minor arc
Arc ABCD is a major arc
Correct Answer: Option AThe next step in simplification will be to convert the squared term so that it no longer contains a square.
So, we are to simplify the term

Using the half-angle identity we can write:

Using this value, the equation becomes:
Therefore, option A is the correct answer.
Two triangle are congruent when the shape and size of both the triangle are same. The given information is the SAS case.
To find the form of the case we need to know about the triangle congruence theorem.
<h3>What is triangle congruence theorem?</h3>
Two triangle are congruent when the shape and size of both the triangle are same.
Triangle congruence theorem are-
- Angle-Side-Angle theorem (AAS)- This theorem states that two triangle is congruent when two angle and one side of the triangle are respectively equal to the two angles and same side of the other triangle.
- Side-Side-Side theorem (SSS)- When the three sides of the one triangle is equal to the three sides of the other triangle respectively, then the triangle are congruent.
- Side-Angle-Side theorem (SAS)- Two sides and the included angle of are equal to the two sides and one angle of other triangle respectively.
Given information-
Evelyn is 104 meters from the take off.
The angle of elevation of the plane is 12°.
The plane is 100 meters away from the takeoff point.
The distance is 100 meters and 104 meters. The other two sides , as are same and the angle of elevation is also same for this case (12 degrees).
Thus the two triangle formed which are congruent.
As above discussed the case of SAS exists for the triangle congruence theorem.
Hence the given information is the SAS case.
