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
trasher [3.6K]

Answer:

The measure of the first angle is 50°.

Step-by-step explanation:

Let the three angles be <em>a, b, </em>and <em>c. </em>

<em />

The measure of the first angle is twice the measure of the second angle. In other words:

a=2b

The measure of the third angle is 80° more than the measure of the second angle. In other words:

c=b+80

And since the interior angles of a triangle must equal 180°:

a+b+c=180

Substitute <em>a</em> and <em>c: </em>

<em />(2b)+b+(b+80)=180<em />

Combine like terms:

4b+80=180

Subtract 80 from both sides:

4b=100

And divide both sides by four:

b=25^\circ

So, the measure of the second angle is 25°.

Since the measure of the first is twice the second, the measure of the first angle is 50°.

(And since the measure of the third is 80° than the second, the measure of the third angle is 105°.)
