The point (-7,4) in on the terminal side of an angle t. Find sec (t) to two decimal places.

Answers

Answer:

  -1.15

Step-by-step explanation:

The tangent of the angle can be found as ...

  tan(t) = (y-coordinate)/(x-coordinate) = -4/7

The secant of the angle is related by ...

  sec(t)² = tan(t)² +1 = (-4/7)² +1 = 65/49

Then the secant of this 2nd-quadrant angle is ...

  sec(t) = -√(65/49) = -(√65)/7 ≈ -1.15

The formula for the length of the hypotenuse in a right triangle is squared a^2+b^2 where a and b are the lengths

Answers

Answer:

the hypotenuse in a right triangle formula is c= sqrt(a^2+b^2)

Step-by-step explanation:

The original Pythagorean's theorem equation is a^2+b^2=c^2 which we can take the square root of to isolate and solve for the equation for just the hypotenuse length. This of course is assuming that a and b are the legs of the triangle. Let me know if this wasn't what you were asking or if you need more clarification and I'll amend my answer
