Answer:
Step-by-step explanation:
For convenience, I labeled some points as shown in the attached picture.
Also, I assume and are tangents to the circle.
- (reflexive property)
- (tangents drawn from a common external point are congruent)
- (right angles are congruent)
Therefore, we know by HL.
Thus, by CPCTC,
This means the measure of minor arc AC is , and thus
The legs are 12 cm each, so the hypotenuse is√(144+144)=12√2☺☺☺☺
Step 3:
5x + 20 + 3x + 9x + 7 becomes
5x + 3x + 9x + 20 + 7
Step 4:
(5x + 3x + 9x) + (20 + 7)
Step 5:
17x + 27

Hope this helps
