1 answer:

8 0

We are given with the point (5,-4) where x is 5 and y is equal to -4. in this case, we can get the six trigonometric identities from this data. the hypotenuse is equal to sqrt 41 accrdg to pythagorean theorem.

cos theta = 5/ sqrt 41
csc theta = -sqrt 41/ 4
tan theta = -4/5

Answer:

Step-by-step explanation:

We know: the sum of the measures of triangle angles is 180°.

Therefore we have the equation:

$2x+(3x-10)+50=180\\\\(2x+3x)+(-10+50)=180\\\\5x+40=180\qquad\text{subtract 40 from both sides}\\\\5x+40-40=180-40\\\\5x=140\qquad\text{divide both sides by 5}\\\\\dfrac{5x}{5}=\dfrac{140}{5}\\\\x=28$

Answer:

Volume of the rectangular prism = 2366 cubic inches

Explanations:

The volume of a prism = Base Area x Height

In this case, the base area is referred to as the face area

Base area = 169 square inches

Height = 14 inches

Volume of the prism = 169 x 14

Volume of the rectangular prism = 2366 cubic inches
