If m∠cad = 12°, cd = 9, and bc = 9, find m∠cab.

question 9 options:

12°

24°

78°

6°

It would be 12 as well

Step-by-step explanation:

If CD=BC then CAD=CAB.

I hope that helps. Let me know if it is right.

Answer : The value of ∠CAB is, 12°

Step-by-step explanation :

The following combinations of the congruent triangle facts  will be sufficient to prove triangles congruent.

The combinations are:

(1) SSS (side-side-side) : If three sides of a triangle are congruent to three sides of another triangle then the triangles are congruent.

(2) SAS (side-angle-side) : If two sides and included angle of a triangle are congruent to another triangle then the triangles are congruent.

(3) ASA (angle-side-angle) : If two angles and included side of a triangle are congruent to another triangle then the triangles are congruent.

(4) RHS (right angle-hypotenuse-side) : If the hypotenuse and leg of one right triangle are congruent to the corresponding parts of another right triangle, the right triangles are congruent.

First we have to prove ΔADC ≅ ΔABC

Prove : ΔADC ≅ ΔABC

As,

Side AB = Side AD    (side = 9)

Side AC = Side AC    (common side)

∠D = ∠B                     (90°)

That means, in this two sides and included angle of a triangle are equal to another triangle then the triangles are congruent.

ΔADC ≅ ΔABC   (by SAS rule)

And, ∠CAD = ∠CAB  (by CPCT)

So, ∠CAD = ∠CAB = 12°

step-by-step explanation:

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
