Help me out the number inside the triangle is really throwing me off tbh
prisoha [69]

We are given an angle of 60° and a side of 15 cm.

We are given the opposite and is looking for the hypotenuse so we will use the sine ratio to find x.

sin = opp/hyp

hyp = 15 / sin 60

hyp = 17.32...

//

We can also use the tangent ratio to find the adjecent and then use pythagorean to find x.

tan = opp/adj

adj = 15 / tan 60

adj = 8.660.....

8.660....² + 15² = 300²

since the square root of 300 is an irrational number, we have to turn it into a mixed radical.

The answer would be the top one.

A line has a slope of 1/4 and passes through point (0.4,-1/2). What is the value of the y-intercept?
AVprozaik [17]

Answer: The value of the y-intercept is -\frac{3}{5}

Step-by-step explanation:

The equation of the line in Slope-intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

In this case we know that the line passes through point (0.4,-\frac{1}{2}) and has a slope of \frac{1}{4}. Then we can substitute the following values into  y=mx+b:

x=0.4\\\\y=-\frac{1}{2}\\\\m=\frac{1}{4}

Then:

-\frac{1}{2}=\frac{1}{4}(0.4)+b

And finally, we must solve for "b":

-\frac{1}{2}=\frac{1}{4}(0.4)+b\\\\-\frac{1}{2}-\frac{1}{10}=b\\\\b=-\frac{3}{5}
