Two interior angles of a scalene triangle measure 85 and 50 degrees. The third angle measures:

zmey [24]

The interior of a triangle = 180°
So 180° - 85° -50° = 45°

c. 45 degrees

Find the area and perimeter

pashok25 [27]

Answer:

Part 1) The perimeter is $P=172\pi\ ft$

Part 2) The area is $A=1,204\pi\ ft^2$

Step-by-step explanation:

Part 1) Find the perimeter

we know that

The perimeter is equal to the circumference of the exterior circle plus the circumference of the interior circle

so

$P=2\pi (50)+2\pi (36)$

$P=2\pi (86)\\P=172\pi\ ft$

Part 2) Find the area

we know that

The area of the figure is equal to the area of the larger circle minus the area of the smaller circle

so

$A=\pi (50)^2-\pi (36)^2$

$A=\pi (1,204)$

$A=1,204\pi\ ft^2$

A pizza slice is in the shape of a circular sector OAB, with the central angle 0 = 50 deg and a radius of 7cm. 0 A B В Find the

Goryan [66]

Answer:

<em>The perimeter of the pizza slice is 20.1 cm</em>

Step-by-step explanation:

<u>Perimeter of a Sector of a Circle</u>

The arc length of a sector of a circle of radius r and angle θ is given by:

L = rθ

The angle must be expressed in radians.

The total perimeter of the circular sector, including the two radii, is:

P = rθ + 2r

The pizza slice has a radius of r=7 cm and a central angle of θ=50°

Converting to radians:

$\theta=50*\frac{\pi}{180}=\frac{5\pi}{18}$

The perimeter is:

$P = 7*\frac{5\pi}{18} + 2*7$

Calculating:

P = 20.1 cm

The perimeter of the pizza slice is 20.1 cm
