If line AD is a tangent to circle B at point C, and m ABC = 55°, what is the measure of BAD?
nikdorinn [45]

Answer:

145°

Step-by-step explanation:

There are a couple of ways you can get there:

1. ∠ACB is a right angle, 90°. Hence, ∠BAC is the complement of ∠ABC, so is ...

... ∠BAC = 90° -∠ABC = 90° -55° = 35°

Then, ∠BAC and ∠BAD are a linear pair, so total 180°. That makes ∠BAD the supplement of ∠BAC, so ...

... ∠BAD = 180° -35° = 145°

2. ∠BAD is the exterior angle at A for the triangle ABC. It will have a measure that is the sum of the opposite interior angles: given ∠ABC = 55° and right angle ACB = 90°.

... ∠BAD = 55° +90° = 145°

Which of these expressionis is <br> equivalent to x^4-5x+3/x^2+7
bonufazy [111]

Next time, please list the possible answer choices.  Without them, all I can do is to attempt this problem without having those choices as guidelines.


I must assume that your expression x^4-5x+3/x^2+7 actually meant:

            5x + 3

x^4  -  ---------------

             x^2 + 7

and I assume that this result was one of the several possible answer choices.
