Please help me. This is the 30°-60°-90° Triangle Theorem.

Mathematics
1 answer:
ziro4ka [17]2 years ago
3 0

Answer:

Tan30° = 4/y

Tan30° = 1/root3

Therefore 4/y = 1/root3

Which gives the value of y 4root3

Which is 6.92 (approx)

As for x

Sin30 =4/x

1/2=4/x

X=8

Solve the equation for solutions over the interval ​[0​°, 360°​).
olchik [2.2K]

Answer:

x=98.13^\circ,135^\circ,278.13^\circ,315^\circ

Step-by-step explanation:

tan^2x+7tanx+8=0,[0^{\circ},360^\circ)

tan^2x+7tanx+8=0

u=tanx <-- U-substitution

u^2+7u+8=0

(u+7)(u+1)=0

(tanx+7)(tanx+1)=0 <-- Replace u with tanx

tanx+7=0

tanx=-7

x=98.13^\circ,278.13^\circ

tanx+1=0

tanx=-1

x=135^\circ,315^\circ

Therefore, x=98.13^\circ,135^\circ,278.13^\circ,315^\circ

What is the angle measure of an arc bounding sector with an area of 5pie square miles?
Snowcat [4.5K]

if the diameter is 20, the its radius must be half that or 10.

\textit{area of a sector of a circle}\\\\ A=\cfrac{\theta \pi r^2}{360}~~ \begin{cases} r=radius\\ \theta =\stackrel{degrees}{angle}\\[-0.5em] \hrulefill\\ A=5\pi \\ r=10 \end{cases}\implies \begin{array}{llll} 5\pi =\cfrac{\theta \pi (10)^2}{360}\implies 5\pi =\cfrac{5\pi \theta }{18} \\\\\\ \cfrac{5\pi }{5\pi }=\cfrac{\theta }{18}\implies 1=\cfrac{\theta }{18}\implies 18=\theta \end{array}
