Answer:

8

Step-by-step explanation:

Use pythagerom therom we know the hypotneusis 10 and the base is 6 so we do 100^2 - 6^2 and get 64 then we take the square root of 64 and get 8

Find the missing side or angle. Round to the nearest tenth.
Ivanshal [37]

Answer:

<h2>A = 22.6°</h2><h2>B = 67.4°</h2>

Step-by-step explanation:

Trigonometry:

S\frac{O}{H} C\frac{A}{H} T\frac{O}{A}

Use Sine when you have the Opposite and the Hypotenuse.

Use Cos when you have the Adjacent and the Hypotenuse.

Use Tan when you have the Opposite and the Adjacent.

The Opposite is opposite the angle.

The Adjacent is next to the angle

The Hypotenuse is opposite the right angle.

<u>Angle A:</u>

Use Tan when you have the Opposite and the Adjacent.

Tan-1\frac{5}{12} = 22.6198... ~ 22.6°

<u></u>

<u>Angle B:</u>

Use Tan when you have the Opposite and the Adjacent

Tan-1\frac{12}{5} = 67.380... ~ 67.4°

22.6° + 67.4° + 90° = 180°

The sides of triangle ABC are 4.5feet 7.5 ft and 9 ft.The area is about 17 square feet. Explain how to use the are of triangle A
Nuetrik [128]
In order to get the area of a triangle using sides, the formula that we are going to use is Heron's formula. This is after from "Hero of Alexandria".
So here is the step by step process:
First, we calculate for s (half of the triangles perimeter) s = a+b+c divided by 2.
s = 6 + 10 + 12 / 2
s =28/2
s = 14
Now that we have the s, we can now calculate for the area.
A = square root of s(s-a)(s-b)(s-c)
A= square root of 14 x 8 x 4 x 2
A= square root of 896
A = 29.93
The area of triangle DEF is 29.93 square feet or 30 square feet. Hope this answer helps.
