Find the leg of each isosceles right triangle when the hypotenuse is of the given measure.Given = 6 square root two cm

Answers

we have given 
hypotenuse=6√2
let us suppose leg =a
using Pythagorean theorem
a^2+a^2=(
6√2)^2
2a^2=36*2
diving by 2 on both sides
a^2=36
taking square root on both sides
√a^2 =√36
a=6
therefore
the leg of each isosceles right triangle is 6

Find the product: 1 1/4×5 3/5.

Answers

The solution to the expression 1 1/4 × 5 3/5 as a fraction is 4 1/2

How to evaluate the expression as a fraction

from the question, we have the following parameters that can be used in our computation:

1 1/4 × 5 3/5

Convert the fractions to improper fraction

So, we have the following

1 1/4 × 5 3/5 = 5/4 × 18/5

Evaluate the product of the fractions

So, we have the following

1 1/4 × 5 3/5 = 1/4 × 18/1

Simplify

1 1/4 × 5 3/5 = 9/2

So, we have

1 1/4 × 5 3/5 = 4 1/2

Hence, the solution as a fraction is 4 1/2

Tony is standing at sea level. From his location, the angle of elevation of the top of Blue Mountain is 23°. Staying at sea level, he walks 220 yards toward the mountain. The angle of elevation of the top is now 27°. Find the height of Blue Mountain. Round intermediate results to 3 decimal places and the final answer to 1 decimal place.

Answers

Answer:

559.2 yards.

Step-by-step explanation:

Let the height of the mountain be x yards and the distance from the second location to the base of the mountain be y yards.

Then we have the equations:

tan 27 = x/y

tan 23 = x / (220 + y)

From the first equation  y =  x/ tan27 so substituting in the second one we have:

tan 23 =  x / (220 + x / tan 27)

Cross multiply:

x = 220 tan23 +  x tan 23 / tan 27

x =  93.384 + 0.833 x

x - 0.833x = 93.384

x = 93.384 / 0.167

x = 559.2 yards to 1 dec place (answer).
