In a triangle , the measure of the first angle is twice the measure of the second angle. The measure of the third angle is 80 mo

Flauer [41]

Answer:

25, 50, and 105.

Step-by-step explanation:

Let the first angle be A, the second angle be B, and the third angle be C.

First, the sum of the three angles in a triangle is 180. Thus:

$A+B+C=180$

We know that the measure of A is twice the measure of B. Thus:

$A=2B$

And the measure of C is 80 more than the measure of B. So:

$C=80+B$

Let's substitute A and C into the original equation:

$2B+B+80+B=180$

Now, let's solve for the second angle (B). Combine like terms:

$4B+80=180$

Subtract 80 from both sides:

$4B=100$

Divide both sides by 4:

$B=25$

So, the second angle is 25 degrees.

This means that the first angle is 2(25) or 50 degrees.

And the third angle is 80+25 or 105 degrees.

And we're done!

The angles are 25, 50, and 105.
