I think by SAS because there is only one angle and two sides
Answer:
15.0
Step-by-step explanation:
Let's start by looking at triangle ORQ. Since RQ is tangent to the circle, we know that angle ∠ORQ is 90°. Then, since OR is equivalent to the radius of 5, RQ is 5√3, and side OQ is clearly larger than RQ, we can identify this as a 90-60-30 degree triangle. This makes side OQ have a length of 10, and angle ∠QOR, opposite of the second largest side, has the second largest angle of 60°, leaving ∠OQR with an angle of 30°.
The formula for the chord length is 2r*sin(c/2), with c being the angle between the two points on the circle (in this case, ∠QOR=∠NOR).. Our radius is 5, so the length of chord NR is 2*5*sin(60/2)=5, making our answer 5(ON)+5(OR)+5(RN)
Answer:
x = 144
Step-by-step explanation:
Sum of all angles of n-sided polygon = 180 * (n - 2)
Sum of all angles of 8-sided polygon = 180 * 6 = 1080
x + 129 + 132 + 136 + 124 + 141 + 158 + 116 = 1080
x + 936 = 1080
x = 1080 - 936
x = 144
