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 )
Answer:
492.52
Step-by-step explanation:
The formula is P(t) = P(0) x (1+r/n)^nt so...
P(t) = 440 (1+0.058/1)^8
P(t) = 492.52
Answer:
12.3
Step-by-step explanation:
You will use cosine to solve for y because you are given the hypontenuse and need to find the adjacent side.
cos 35 degrees = adjacent/hypontenuse
cos 35 = y/ 15
15( cos35 ) = y
y=12.287
=12.3
