Part of a school’s stage is shaped like a sector of a circle, as shown below. The students do not yet know the exact dimensions

Natasha2012 [34]

Answer:

68.78° or 0.6 rad

Step-by-step explanation:

Use the formula:

degrees/360° = L/circumference
or
radians/π = L/circumference

As per given:

l = 12 feet, r = 10 feet

degrees = 360°*12/(2*3.14*10) = 68.78°
radians = π rad *12/(2π*10) = 0.6 rad

Aleksandr-060686 [28]

Answer:

$\tan D=\frac{7}{4},\\\\\sin D=\frac{7}{8.1}, \\\\\cos D=\frac{4}{8.1}, \\\\GI=5.0$

Step-by-step explanation:

In any right triangle, the following is true:

The sine of any angle is equal to its opposite side divided by the hypotenuse of the triangle. (o/h)

The cosines of any angle is equal to its adjacent side divided by the hypotenuse. (a/h)

The tangent of any angle is equal to its opposite side divided by its adjacent side. (o/a)

Thus,

$\text{3. }\\\tan D=\frac{7}{4},\\\\\sin D=\frac{7}{8.1}, \\\\\cos D=\frac{4}{8.1},$

$\text{4. }\tan 68^{\circ}=\frac{GI}{2},\\GI=2\tan68^{\circ}=4.95017370683\approx \boxed{5.0}$

Question 1

Vikki [24]

Answer:

(B)15,36,39

Step-by-step explanation:

To determine which of the line segments could create a Right Triangle, we check if it satisfies the Pythagoras Theorem, taking the longest part to be the Hypotenuse in all cases.

By Pythagoras Theorem: $Hypotenuse^2=Opposite^2+Adjacent^2$

In 15,30,35

$35^2\neq 15^2+30^2\\1225\neq 1125$

In 15,36,39

$39^2=36^2+15^2\\1521=1521$

In 15, 20, 29

$29^2\neq 15^2+20^2\\841\neq 625$

In 5,15,30

$30^2\neq 15^2+5^2\\900\neq 250$

We can see that only 15,36,39 satisfies the required condition and thus it could be used to create a right triangle.
