Line Q, you always want the line that has as many dots on it as possible!! :)
The 3rd one
You can factor 3 out of each term in the numerator. And then divide it by the 3 in the denominator.
We know the measure of one of the angles.Angle b which is 90.
Now we have to find the other two angles.
First we will find angle a.
There are 180 degrees in a straight line.
Sooo...
180-130=50
Angle a will be 50.
There are also 180 degrees in a triangle.
To find the last angle we do this
180-50-71=59
Your answer and the measure of angle c will be 59 or option 3.
