Answer:
a. 90º
Explanation:
The chords ST and RA intesect at Y, so that SY is now perpendicular to RY and they form an angle 90 degrees at that point. However angles mSA and mRT are both at the circumference of the circle(a chord is a line from point of a circle's circumference to the other) and are both 90 degrees because angle at the circumference is half of angle at the centre in same arc.

Answer:
6.33 m
Step-by-step explanation:
Total length of the rope = 8 m
Cut length of the rope = 1.67 m
We need to find the remaining piece of the rope.
Remaining piece = Total length - cur length
= 8 m - 1.67 m
= 6.33 m
So, 6.33 m is the remaining piece of the rope.
Answer:
the answer is 123 123+156=279.
