Line AC is tangent to circle O at point C What is the measure of OAC?

Mathematics

Nuetrik [128]3 years ago

AC is a tangent so by definition, it touches the circle at exactly one point (point C) and forms a right angle at the tangency point. So angle ACO is 90 degrees

The remaining angle OAC must be 45 degrees because we need to have all three angles add to 180
45+45+90 = 90+90 = 180

Alternatively you can solve algebraically like so
(angle OAC) + (angle OCA) + (angle COA) = 180
(angle OAC) + (90 degrees) + (45 degrees) = 180
(angle OAC) + 90+45 = 180
(angle OAC) + 135 = 180
(angle OAC) + 135 - 135 = 180 - 135
angle OAC = 45 degrees

Side Note: Triangle OCA is an isosceles right triangle. It is of the template 45-45-90.

The angle m∠ABC is 70 degrees.

<h3>How to find angle in a rhombus?</h3>

The angle in a rhombus can be found as follows;

The opposite angle of a rhombus are congruent.

Therefore,

∠B = 140 degrees

Hence, the diagonal of a rhombus bisect an angle.

Therefore,

m∠ABC = 140 / 2

m∠ABC = 70 degrees.

Pre calculus <br> Will every function have a hole? Why or why not?
kodGreya [7K]

Answer:

No, not every function will have a hole. This is considered a special case.          A typical function is one that can be written as a fraction of two polynomials where the denominator is not zero. In a special case (when there is a hole), a factor may appear in both the numerator and denominator.

If you subtract 25,974 from 29,148 than you would get your answer 3,174. 3,174 would be the difference between the the two games.

This is easy i’m just dumb please help
9966 [12]
Hello! I can help you with this! So what we need to do is convert fractions to decimals. If you know basic fractions, 1/4 = 0.25, And 1/5 = 0.2. In this case, here are the numbers converted into decimal form.

8 1/4 = 8.25
1 1/5 = 1.2
2 1/4 = 2.25
6 1/5 = 6.2

Now this question is asking for the perimeter around the figure. In this case, we have to add up all of the sides. When we add up all of the numbers, you should get 17.9 or 17 9/10 in simplest fraction form. There. The perimeter is 17 9/10 meters.
