Answer:
∴ ∠BAD = 
(0.2044) = 11.8°
Step-by-step explanation:
i) AD = 9 cm
ii) DC = 3 cm
iii) ∠BCD = 35°
iv) Since AB is parallel to DC and ∠ABD = 90° then we can conclude that ∠BDC = 90°.
v) 
= 0.6128 ∴ BD = 3 
0.6128 = 1.84 cm
vi) ∴ sin(∠ BAD ) = 
⇒ sin(∠ BAD ) = 
= 0.2044
∴ ∠BAD = (0.2044) = 11.8°
64 - 9 = 55 \sqrt{55} = 7.4161984871
7.4161984871/2 ≈3.7
Sin60=DF/FE
Root 3/2= DF/ 18 Root 3
DF= 18*3/2
DF= 27 units
cos60=DE/FE
1/2=DE/18 Root 3
DE= 18 Root 3/2
DE= 9 Root 3 units

22.803
Step-by-step explanation:
multiple 30% by 76.01 equals 22.803
Answer:
$62,167.3
Step-by-step explanation:
Profit after nine years is the amount.
Amount = Principal + Interest
Given
Earning profit = Principal = $49,300
Rate = 2.9%
Time = 9 years
Interest = Principal * Rate * Time/100
Interest = $49,300*2.9*9/100
Interest = 1,286,730/100
Interest = $12,867.30
Amount = $49,300+$12,867.30
Amount = $62,167.3
Hence leroys profits after nine years is $62,167.3
