To solve this problem, we use the tan function. The distance
across the river is the adjacent side, the distance drownstream is the opposite
side while the direction of the boat is the hypotenuse.
tan θ = opposite side / adjacent side
tan 10 = opposite side / 420 ft
opposite side = 74.06 ft
<span>Therefore the boat will move about 74 ft downstream.</span>

Answer:
y = 20·2^x
Step-by-step explanation:
Use the given points to write two equations, then solve for 'a' and 'b'.
20 = a·b^0 = a
5120 = a·b^8 = 20·b^8 ⇒ 256 = b^8
b = 256^(1/8) = 2
Your function is ...
y = 20·2^x
I’m going to say A
Sorry if I’m wrong
Answer:
124°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Subtract the sum of the 3 given angles from 360
missing angle = 360° - (48 + 91 + 97)° = 360° - 236° = 124°
