Answer:

14.04º

Step-by-step explanation:

Since it is a right-angle triangle, we can apply the trigonometry identity.

The Tangent rule state that Tan (θ) = Opposite/Adjacent

In the diagram, the opposite (the side that is opposite of the θ) is 5 units.

The adjacent (the side that is along the θ) is 20 units.

Applying the identity,

Tan (θ) = 5/20

θ = 14.04º (nearest hundredth)

Find the area of the polygon.

Answer:

2,400 cm²

Step-by-step explanation:

You can solve for x because you know that 40cm=x²+4cm:

36 cm = x²

x = 6cm.

Therefore the width is 2(6)²-12, which is 60cm.

So the area is 40 cm x 60 cm, which is 2,400 cm².

Answer:

$\huge\boxed{c)\ 15,\ 36,\ 39}$

Step-by-step explanation:

$\text{Let}\ a\leq b\leq c\ \text{the sides of the triangle}.\\\\\text{If}\ a^2+b^2=c^2\ \text{then a triangle is a right triangle}\\\\\text{If}\ a^2+b^2c^2\ \text{then a triangle is a acute triangle}$

$a)\ 28,\ 45,\ 53\\\\28^2+45^2=784+2025=3593\\53^2=2809\\\\28^2+45^2>53^2\to\text{acute triangle}\\\\b)\ 17,\ 22,\ 29\\\\17^2+22^2=289+484=773\\29^2=841\\\\17^2+22^2$
