Answer:
The area of the triangle is six square metres.
Step-by-step explanation:
The area of the triangle is half the area of the rectangle that it fits in. This one is particularly simple, as it's a right triangle and we're given its width and height, so it's area is:
w × h ÷ 2
= 3 × 4 ÷ 2
= 3 × 2
= 6
Answer:
x is equal to 15.
Step-by-step explanation:
In order to solve this, we need to set it up as a proportion.
6/8 = x/20
Now that we have the proportion, we need to cross multiply to solve.
6*20 = 8*x
120 = 8x
15 = x

The distance to the earth’s horizon from point P is 281.6 miles
<h3>How to determine the distance to the earth’s horizon from point P?</h3>
The tangent line from P meets the radius of the earth at a right angle.
This means that the triangle is a right triangle.
The length of x is then calculated as:
(3959 + 10)^2= 3959^2 + x^2
Rewrite as:
x^2 = (3959 + 10)^2- 3959^2
Evaluate
x^2 = 79280
Take the square root of both sides
x = 281.6
Hence, the distance to the earth’s horizon from point P is 281.6 miles
