1 answer:

4 0

To determine the equivalent ratios, we would reduce each ratio to its lowest term. This involves dividing by a common factor till it is no longer divisible. Therefore,

A flag pole and its shadow form the sides of a right triangle. If the hypotenuse is 35m long and the shadow is 28m, how tall is

castortr0y [4]

Answer:21 m

Step-by-step explanation:

Given

A flag pole and its shadow form the sides of a right triangle

Hypotenuse=35 m

Shadow length=28 m

As the Triangle is right angle therefore we can apply Pythagoras theorem.

Let pole length be x

$x^2+(28)^2 =(35)^2$

$x^2=1225-784=441 m$

$x=\sqrt{441}=21 m$

Determine if the sequence below is arithmetic or geometric and determine the

Brrunno [24]

The sequence is arithmetic since the common difference that is equal
d=11-15=7-11=-4
a(n) = a1 +(n-1)d
a1=15
=
a(n) = 15+(n-1)-4

1. What is the value of x in the figure?

irinina [24]

Answer:

$x=6\sqrt{5}\\ \\y=3\sqrt{5}\\ \\z=6$

Step-by-step explanation:

The height of the right triangle drawn to the hypotenuse is geometric mean of two segments of hypotenuse, so

$z^2=12\cdot 3\\ \\z^2=36\\ \\z=6$

By the Pythagorean theorem,

$x^2=12^2+z^2\\ \\x^2=144+6^2\\ \\x^2=144+36\\ \\x^2=180\\ \\x=6\sqrt{5}$

and

$y^2=z^2+3^2\\ \\y^2=6^2+9\\ \\y^2=36+9\\ \\y^2=45\\ \\y=3\sqrt{5}$
