Answer:
m∠U = 103° and m∠TRS = 6°
Step-by-step explanation:
In the given circle O,
Since, RS║VU, and VR is a transverse,
Therefor, m∠V + m∠R = 180° [Consecutive interior angles]
m∠R + 103° = 180° [m∠R = 103° given]
m∠R = 180° - 103°
m∠R = 77°
Since m∠R = m∠VRT + m∠TRS
77° = 71° + m∠TRS
m∠TRS = 77° - 71° = 6°
Quadrilateral RTUV is a cyclic quadrilateral.
Therefore, m∠U + m∠R = 180°
m∠U + 77° = 180°
m∠U = 180° - 77° = 103°

Answer:
85%
Step-by-step explanation:
- Calculate how many students passed on their first try. 20 x 70% is 14, so 14 students passed on their first try.
- 6 students retook the test. Half of 6 is 3. Add 3 to the 14 students that passed earlier.
- Calculate the percent with the equation 17/20 = 0.85. 0.85 = 85%.
This is the equation. Try it for yourself and see if it works.
C= n x 4
