Question

The sum of the three angles of a triangle is 180°. Two angles of a triangle measure 15 and 73. Of x is the third angle, set up and solve an equation to find out what the measure of the third angle?

Answer 1

The measure of the third angle is 92°

Explanation:

We first have to make an equation that represents this equality. To do it we simply have to add the values ​​that give us with x and this will result in 180 °

15° + 73° + x = 180°

once we have the equation what we have to do is solve x, so we will pass all the terms that are adding to x by subtracting 180

x = 180° - 73° - 15°

now that we have cleared the x we ​​only have to perform the indicated operation and we will obtain the value of x

x = 92°

The measure of the third angle is 92°
