Answer: The answer is (A). Similar.

Step-by-step explanation:  We are given two triangles, ΔABC and ΔDEF where, ∠B = 80°, ∠C = 60°, ∠D = 40° and ∠E = 80°.

We are to check whether the two triangles are similar or not.

In ΔABC, we have

\angle A+\angle B+\angle C=180^\circ\\\\\Rightarrow \angle A+80^\circ+60^\circ=180^\circ\\\\\Rightarrow \angle A=180^\circ-140^\circ\\\\\Rightarrow \angle A=40^\circ,

and in ΔDEF, we have

\angle D+\angle E+\angle F=180^\circ\\\\\Rightarrow 40^\circ+80^\angle F=180^\circ\\\\\Rightarrow \angle F=180^\circ-120^\circ\\\\\Rightarrow \angle F=60^\circ.

Therefore, in ΔABC and ΔDEF, we have

∠A = ∠D,

∠B = ∠E,

∠C = ∠F.

So, by AAA similarity postulate, we get

ΔABC ≈ ΔDEF.

Thus, (A) is the correct option.

A similar because all triangles add up to 180 ,

they both have 80 so leaves 100 degrees left..

and they both have the same #'s 80, 60, & 40 degrees equal to 180 degrees

How can you decompose the composite figure to determine its area?
Gnom [1K]

Answer:

as two semicircles and a rectangle

Step-by-step explanation:

If you extend the radii shown, each becomes an end of the rectangle, and also a boundary for a semicircle. The result is two semicircles and a rectangle.

_____

Of course, two semicircles make a circle, so you could also decompose this to a circle and a rectangle.

What is the value of x?
Westkost [7]

Answer:

x is equal to 20 in this picture.

Step-by-step explanation:

In order to find this, we need to note that these two angles will be equal to each other. Now we can put their values equal to each other and solve for x.

3x + 50 = 6x - 10

50 = 3x - 10

60 = 3x

20 = x
