Answer:
X^2 + 70x + 12000
Step-by-step explanation:
Is that what you wanted? I got that by using the distributive method.
The answer is 48 because 1.6 times 30 is 48
Answer:
Square root of 269 or 16.4
Step-by-step explanation:
Use the distance formula
Answer:
The wide is 70.02 m.
Step-by-step explanation:
First you need to draw a triangle with only one 90 degrees angle.
The opposite side to the 90 degrees angle will be the hypotenuse.
We will call the remaining sides ''Baseline'' and ''River wide''.
The angle between hypotenuse and baseline is 35 degrees.
The triangle has one 90 degrees angle so we can apply the tangent equation
in the angles that are no 90 degrees.
Tangent (angle) = Opposite side/adjacent
Tan(35°)= River wide/100m
River wide = 100m.Tan(35°)
River wide = 70.02 m
