Answer:
Option B
3.5 miles
Step-by-step explanation:
Considering the picture attached, the distance to Cascade Falls is written in mixed fraction and the question wants it expressed in decimal. 
is same as 1 divided by 2 which is 0.5 hence the fall is 3+0.5=3.5 miles
The answer to your question is X = -8
Answer:
Hence x = y = 2
Step-by-step explanation:
Using the SOH CAH TOA identity
Hypotenuse = 2√2
Opposite = x
theta = 45
Sin theta = opp/hyp
Sin 45 =x/2√2
1/√2 = x/2√2
x = 2√2 * 1/√2
x = 2
To get y we will use the pythagoras theorem;
(2√2)² = x² +y²
(2√2)² = 2²+y²
8 = 4 + y²
y² = 8-4
y² = 4
y = √4
y = 2
Hence x = y = 2
