Answer:
0.3 or 3/10
Step-by-step explanation:
100%=1 so 30%=0.3
5.2x10^6 is the right answer because the decimal is moved 6 times to the right which makes the 5 the first number because it can’t be more than 10

Answer:
- vertex: S
- sides: ST and SR
Step-by-step explanation:
The vertex is the point the rays have in common. The side rays are named by naming the vertex first, then a point on the ray.
The rays come together at point S. The name of the vertex point is S.
The sides of the angle are rays ST and SR.
Answer:
(a) 46°
(b) 86°
Step-by-step explanation:
When the secants cross externally (figure a), the angle where they cross is half the difference of the subtended arcs.
When they cross internally (figure b), the angle is half the sum of the subtended arcs.

<h3>(a)</h3>
Half the difference of arcs VW and VX is ...
∠VYW = 1/2(160° -68°) = 46°
m∠VYW = 46°
__
<h3>(b)</h3>
Half the sum of arcs AB and CD is ...
∠CED = 1/2(arc AB +arc CD)
2×∠CED = arc AB +arc CD . . . . . multiply by 2
2×∠CED -arc AB = arc CD . . . . . subtract arc AB
arc CD = 2×85° -84° = 86°
m arc CD = 86°
