Answer:
Step-by-step explanation:
1). In ΔABC,
For angle A as a reference angle,
Opposite side of ∠A → BC
Adjacent side of ∠A → AC
Hypotenuse → AB
2). By using tangent ratio in ΔYWZ,
tan(72°) = 
tan(72°) = 
x = 
x = 3.899
x ≈ 3.9
3). By using sine rule in ΔKNM,
tan(x°) = 
tan(x) = 
x = 
x = 19.03
x ≈ 19.0°
4). By applying cosine ratio in ΔJKF,
tan(70°) = 
tan(70) = 
x = 
x = 21.838
x ≈ 21.8
Answer:
D
Step-by-step explanation:
I just did this lol
Given:
Rate of simple interest = 5%
Time = 4 years
Total interest = $160
To find:
The amount borrowed by Austin from a credit union.
Solution:
The formula for simple interest is:

Where, P is principal, r is the rate of interest and t is the number of years.
Putting
in the above formula, we get



Multiply both sides by 5.

Therefore, Austin borrowed $800 from a credit union for 4 years.
Answer:
42
Step-by-step explanation:
so you do 7 times 6 and you should get 42
