One angle in a linear pair is 70 degrees. What is the second angle.?

Answer 1

Jayden Jackson

The second angle in a linear pair with an angle of (70^\circ) would be (180^\circ - 70^\circ = 110^\circ).

#110˚#

This is a pair of linear angles. Linear angles always form a line—that is, they form #180˚#, or a straight angle.

Therefore, the angle in the linear pair with the #70˚# angle must have a combined sum with the #70˚# angle of #180˚#.

We can write this as #70˚+x˚=180˚#, where #x˚# is the measurement of the other angle in the linear pair.

If we take the equation and subtract #70˚# from both sides, we see that #x˚=110˚#, which is the measure of the second angle.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
