Answer:
The length of x in the simplest radical form with a rational denominator will be:
Step-by-step explanation:
Given
hypotenuse = 5
angle Ф = 60°
To determine
x = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
here
Ф = 60°
adjacent of 60° = x
hypotenuse = 5
so substituting Ф = 60°, adjacent = x and hypotenuse = 5 in the equation
cos Ф = adjacent / hypotenuse
so
switch sides
Multiply both sides by 5
Simplify
Therefore, the length of x in the simplest radical form with a rational denominator will be:
Answer:
y=4x+3
Step-by-step explanation:
The slope of the line is (13-7)/(2-1)=4. The line equation is hence y=4x+3
Answer:
You must subtract all terms of the numerator being subtracted out, not just the first term.
The negative 2 should have been subtracted out to get a numerator of x+1-x+2
The simplified numerator of the difference should be 3, not –1.
