You sight a rock climber on a cliff at a 32 to the power of degree angle of elevation. Your eye level is 6 ft above the ground a

nd you are 1000 ft from the base of the cliff. What is the approximate height of the rock climber from the ground. Round to the nearest foot.

The problem above is modelled in the diagram below

The distance of the climber from the ground is x+6ft, where 6 ft is the height of the observer from the ground

We use the trigonometry ratios to work out x

tan(32)= \frac{x}{1000}
x=1000tan(32)
x=625 ft (to the nearest integer)

Hence, the height of the climber from the ground is 625+6 = 631 ft

Points are: A= (-2,7)B= (3,5)C= (1,0) To show that the triangle is a right triangle, show that the sum of the squares of the len
Gala2k [10]

The sum of the squares of the lengths is 58

The square of length of the hypotenuse is 58

From the question, we have

AB² = (-2-3)² +(7-5)²= 25+4 =29

BC² = (3-1)²+(5-0)²=4+25=29

AC² = (-2-1)²+(7-0)² = 9+49 = 58

Here we can see that,

AB²+BC² = AC²

The sum of the squares of the lengths of two sides (the legs) equals the square length of the third side (hypotenuse).

the sum of the squares of the lengths = AB²+BC² =29+29 = 58

the square of length of the hypotenuse= 58

Pythagoras Theorem:

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.

The width of a rectangle is 7 less than twice the length. If the perimeter of the rectangle is 43.6 inches, what is the area of
fgiga [73]

half of 43.6 is 21.8  

9.6+12.2=21.8

9.6 length

12.2 width

9.6*12.2=117.12

so the area would be 117.12
