So, Cot is negative in second and fourth quadrant.
So, tan(x+
)=-cot(x)
Option B
3/4 = x / 340....3 to 4 students = x to 340 students
cross multiply
(4)(x) = (3)(340)
4x = 1020
x = 1020/4
x = 255 <==
or this way.....
3 out of 4 students.....3/4 = 75%
so 75% of 340 = 0.75(340) = 255 <=
Answer:
3/1
Step-by-step explanation:
you need to count the hight of the line from the (0,2) which will be 3 and then how much of the distance of x is. I used rise over run.
He can either measure the third side length, apply the Pythagorean theorem to find the height of the triangle, and then calculate the area, or he can find the measure of the included angle between the known side lengths and use trigonometry to express the height of the triangle and then determine the
area of the triangle
