Answer:
equal to
Step-by-step explanation:
Put both values into a ratio
P:B
28:79
The opposite angles of a quadrilateral inscribed in a circle adds up to 180°.
This means that angles A and C add up to 180°, so do angles B and D.
Therefore, (x - 10) + (x - 2) = 180°
2x - 12 = 180°
2x = 192°
x = 96°
Hence,
Angle A = 96° - 10° = 86°
Angle B = 180° - (96° + 2°) = 82°
Angle C = 96° - 2° = 94°
Angle D = 96° + 2° = 98°
Answer:
0.77
Step-by-step explanation:
If you had to round to the nearest tenth, 0.89 would round to 0.9. 0.74 would round down to 0.7. 0.85 would also round up to 0.9, which leaves the last answer, 9.77 to be rounded to 0.8. Hope this helps
