Answer 19:1
Work:
Students scoring above 80 -
9+18+72+15= 114
Students score exactly 80-
6
114/6 = 19
19 students scored above 80 for every 1 student that scored exactly 80.
Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180 for A
A = 180° - (90 + 46)° = 180° - 136° = 44°
----------------------------------------------------------------
tan46° =
= 
Multiply both sides by 23
23 × tan46° = b, thus
b ≈ 23.8 ( to the nearest tenth )
-----------------------------------------------------------------
cos46° =
= 
Multiply both sides by c
c × cos46° = 23 ( divide both sides by cos46° )
c =
≈ 33.1 ( to the nearest tenth )
