Find the measures of the angles of a triangle whose angles have a measure of x, 1/2x, and 1/6x. Also, what kind of triangle is i

Alexandra [31]

the sum of the angles in a triangle = 180°, thus

x + $\frac{1}{2}$ x + $\frac{1}{6}$ x = 180

multiply through by 6

6x + 3x + x = 1080

10x = 1080 ( divide both sides by 10 )

x = 108

the angles are 108°, 54° and 18°

Since all the angles are different and the largest is 108°

The triangle is an obtuse scalene triangle

What is the period of y = 8 cos (5pie x + 3pie/2)-9<br> Give an exact value. Units

zzz [600]

$\\ \rm\Rrightarrow y=Acos(Bx+C)+D$

This is the general formula and the period is 2π/B

Now our given function

$\\ \rm\Rrightarrow y=8cos\left(5\pi x+\dfrac{3\pi}{2}\right)-9$

On comparing we get

A=8
B=5π
C=3π/2
D=-9

Period:-

$\\ \rm\Rrightarrow \dfrac{2\pi}{B}$

$\\ \rm\Rrightarrow \dfrac{2\pi}{5\pi}$

$\\ \rm\Rrightarrow \dfrac{2}{5}$
