Confused on this work
Anit [1.1K]

We know that :

⊕  Sum of the interior angles in a Pentagon should be equal to 540°

⇒  x° + (2x)° + (2x)° + 90° + 90° = 540°

⇒  (5x)° = 540° - 180°

⇒  (5x)° = 360°

\sf{\implies x^{\circ} = \dfrac{360^{\circ}}{5}}

⇒ x° = 72°

If sin Θ = negative square root 3 over 2 and π < Θ < 3 pi over 2, what are the values of cos Θ and tan Θ? cos Θ = negative
andreev551 [17]

Answer:

The correct option is the option with:

cos Θ = 1/2

tan Θ = -√3

Step-by-step explanation:

Given that

sin Θ = -√3/2

We want to find the values of

cos Θ and tan Θ

First of all,

arcsin (-60) = -√3/2

=> Θ = 60

tan Θ = (sin Θ)/(cos Θ)

tan Θ = (-√3/2)/(cos Θ)

cos Θ tan Θ = (1/2)(-√3)

Knowing that Θ = -60,

and cos Θ = cos(-Θ), comparing the last equation, we have

cos Θ = 1/2

tan Θ = -√3

A. 34cm^3<br> b. 1560cm^3<br> c. 104cm^3<br> d 676cm^3
Vanyuwa [196]

Answer:

676 cubic cm choice d

Step-by-step explanation:

Base area times height gets volume

Base area =  (1/2)*13 * 8  =  52 sq. cm   (area of the right triangle)

height = 13 cm  here

Volume = 13 cm * 52 sq. cm = 676 cubic cm
