Answer:

The angle between the 190 ft. side and the 330 ft. side is 57.9^o

Step-by-step explanation:

<u>The Law of Cosines</u>

When we know the value of all sides of a triangle, we can compute all of its interior angles by using the Law of Cosines, which is a generalization of the Pythagoras's theorem. If a,b, and c are the known sides of a triangle and \alpha is the angle formed by sides a and b (opposite to c), then

\displaystyle c^2=a^2+b^2-2ab\ cos\alpha

We'll use the values a=190, b=330, c=280 because we want to compute the angle opposite to c

\displaystyle cos\alpha =\frac{a^2+b^2-c^2}{2ab}

\displaystyle cos\alpha =\frac{190^2+330^2-280^2}{2(190)(330)}

\displaystyle cos\alpha =\frac{36100+108900-78400}{125400}

\displaystyle cos\alpha =\frac{66600}{125400}=0,5311

\displaystyle \alpha= arccos\ 0.5311

\boxed{\displaystyle \alpha= 57.9^o}

Use a reference angle to write sec255∘ in terms of the secant of a positive acute angle. Do not include the degree symbol in you
jarptica [38.1K]

Answer: sec (75) or csc (15)

Step-by-step explanation:

255 is in the 3rd quadrant where the secant is. Here, the tangent and cotangent is positive.

Reference angle for 255 is,

255 - 180 = 75 degrees.

Therefore, sec (255) = sec (75)

= csc (90 - 75) = csc (15)
