Answer:
see below
Step-by-step explanation:
You found that when secants/chords meet <u>inside</u> the circle, the angle where they meet is <em>half the </em><u><em>sum</em></u> of the intercepted arcs.
When the secants/tangents meet <u>outside</u> the circle, the angle where they meet is <em>half the </em><u><em>difference</em></u> of the intercepted arcs.
The working shown is good as far as it goes. The difference needs to be multiplied by 1/2.
The angle is (122° -70°)/2 = 52°/2 = 26°.
Answer:
x-4 and x+8
Step-by-step explanation:
Factoring a quadratic equation of the form x^2+bx+c:
Divide b into two numbers p and q, so that p+q = b and p*q = c
8 + (-4) = 4 = b
8 * (-4) = -32 = c
x^2+8x-4x-32
Factor by grouping
(x^2+8x)+ (-4x-32) =
x*(x+8) + -4* (x+8) = (x-4)(x+8)

Answer:
(b) ... confirm ∠C≅∠E
Step-by-step explanation:
The first step is to read and understand the problem statement. It is asking for a way to prove ΔABC ~ ΔADE by AA similarity. That means you want to show any two of the three ...
For this purpose, lengths of line segments are irrelevant (eliminating the last two answer choices). The fact that ∠A≅∠A is given, so you only need to find an answer choice that will show one of the last two angle congruences.
Obviously, showing ∠B≅∠E (choice A) is not relevant to the problem.
The only answer choice that is relevant to the question is the second one, showing ∠C≅∠E.
