Answer:

AAA and SSA.

Step-by-step explanation:

The triangle congruence theorems that we have involving the sides and angles of a triangle are:

SSS (side-side-side);

SAS (side-angle-side);

AAS (angle-angle-side); and

ASA (angle-side-angle).

If we had AAA, angle-angle-angle, all we would be able to prove is that the triangles are similar. This does not prove congruence.

If we had SSA, side-side-angle, it will only work sometimes. If the side which lies on one ray of the angle is shorter than the other side (not on the ray of the angle), the two triangles will be of the same shape and size (congruent).

If the side which lies on one ray of the angle is longer than the other side, and the other side is the minimum distance needed to create a triangle(by the triangle inequality theorem), the two triangles will be congruent.

If the side which lies on one ray of the angle is longer than the other side, and the other side is greater than the minimum distance needed to create a triangle (by the triangle inequality theorem), the two triangles will not necessarily be congruent.

If the side which lies on one ray of the angle is longer than the other side, and the other side is less than the minimum distance needed to create a triangle (by the triangle inequality theorem), no triangle can be drawn. Since no triangles are possible, no congruent triangles are possible.

What is the image of (-9,0) after a reflection over the line y=x

SpyIntel [72]

Answer:

(0,-9)

Step-by-step explanation:

The image of a point $(x,y)$ over a line $y=x$ is given by the co-ordinate rule:

$(x,y)$ → $(y,x)$

So, when we reflect a point over the line $y=x$ , the x co-ordinate and y co-ordinate change their places.

Here, $(x,y)$ is $(-9,0)$ . So, from the above rule, after reflection over the line $y=x$ , the image has the following co-ordinates:

$(0,-9)$

Please help me find the total area of the composite figure below (geometry)

Akimi4 [234]

Answer:

lw + $\frac{1}{2}$ × π × $(\frac{l}{2} )^{2}$ ⇒ Answer D is correct

Step-by-step explanation:

First, let us find the area of the semi-circle.

Area = $\frac{1}{2}$ × π × r²

Given that,

diameter of the semi-circle is ⇒ l

∴ radius ⇒ l / 2

Let us find it now.

Area = $\frac{1}{2}$ × π × r²

Area = $\frac{1}{2}$ × π × $(\frac{l}{2} )^{2}$

Secondly, let us find the area of the rectangle.

Area = length × width

Given that,

length ⇒ l

width ⇒ w

Let us find it now.

Area = length × width

Area = l ×w

Area = lw

And now let us find the total area.

Total area = Area of the rectangle + Area of the semi - circle

Tota area = lw + $\frac{1}{2}$ × π × $(\frac{l}{2} )^{2}$

If A's income is 25% less than that of B, then how much percent is B's income more than that of A?

saul85 [17]

Let's say that B makes $100.

Then A makes $75.

So, your question then becomes 100 is what percent of 75?

This can be solved by setting up the proportion 100 / 75 = x / 100

75x = 10000

x = 133.3

So, B's income is 33.3% more than A's income.
