There are 5 ways to test if two figures are congruent, namely;
side-angle-side(SAS)
Angle-side-angle (ASA)
Angle-angle-side(AAS)
Hypotenuse-leg (HL)
3 Sides (SSS)
here we shall focus on SSS. When the three corresponding sides of 2 figures say a triangle have the same length we will conclude that the triangles are congruent by SSS.
Therefore from our choices we can conclude that triangles ABC and ADC are only congruent if the two other side have the same length and BC=DC.
The answer is yes;
B] Yes, but only if BC=DC
If one of the exterior angles is 40, you can find its adjacent interior angle by subtracting 40 from 180. This is 40, so the triangle has 2 interior angles that are equal to 40. Now we have 2 of 3 interior angles. The sum of the measures of the interior angles of a triangle is 180, so we can set this equation up:
x + 40 + 40 = 180
x + 80 = 180
x = 100
So the triangle's angles have measures of 40,40 and 100 degrees.
Answer:
The size of the sample is 23 scientists.
Answer:

Step-by-step explanation:
To find the inverse of a function, we must substitute in y for f(x), swap the locations of y and x, and then solve for y

<span>There is no way to get an exact answer. It could be a really small rhombus, or a huge one, and still have a 46º angle there. You need at least one length of a segment.
Your problem could have errors that's why it can't be solved. You do not have to worry because it happens sometimes.
I hope it helps you.</span>
