Answer:

Area of ΔPQR = 25 units

Step-by-step explanation:

We will use the following formula to calculate the area of triangle ΔPQR:

A = 1/2 | x₁(y₂-y₃) + x₂(y₃-y₁) + x₃(y₁-y₂) | = 1/2 |(-6(1+3) +2(-3-7) +(-1)((7-1)| =

A = 1/2 |-6 · 4 + 2 · (-10) + (-1) · 6| = 1/2 | -24-20-6| = 1/2 | -50| = 1/2 · 50 = 25

A = 25 units

A polygon has an interior angle sum of 2520゚. How many side must the polygon have
Alexus [3.1K]

Answer:

16

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here the sum is 2520, thus

180° (n - 2) = 2520 ( divide both sides by 180 )

n - 2 = 14 ( add 2 to both sides )

n = 16

The polygon has 16 sides.

Find x. Round your answer to the nearest tenth of a degree.<br> x
NeTakaya

Answer:

x ≈ 48.2°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos x = \frac{adjacent}{hypotenuse} = \frac{6}{9} , then

x = cos^{-1} ( \frac{6}{9} ) ≈ 48.2° ( to the nearest tenth )
