Question

Please help

Answer 1

To start, this triangle is obviously not a right triangle or 90 degrees for the corner angle because all angles of a triangle add up to 180. 180- (60 + 25) doesn't equal 90

Answer 2

We can eliminate a and b

Answer 3

So it is D?

Answer 4

I agree with your answer. It isn't d because it's not an acute angle.

Answer 5

Ohh, okay. Thank you!

Read the wording carefully. Notice how it says \(\overset{\leftrightarrow}{BC} \ \underline{\textbf{is}} \text{ a tangent line}\)

I've found my answer, Thank you Jim!

Answer 10

Tangent lines are perpendicular to the radius, so if you can show angle ABC is 90 degrees, then you have a tangent line

Note how for triangle ABC, we can say
A+B+C = 180
25+B+60 = 180
Solve for angle B. If you get 90, then angle ABC is 90 degrees and we have a tangent

Answer 11

No problem
