In a right triangle with a leg of 4 and a hypotenuse of 8, find the measures of all angles.

The measures of all angles are

Step-by-step explanation:

we know that

In a right triangle

Applying the Pythagoras theorem

where

c is the hypotenuse

a,b are the legs

In this problem we have

Find the value of b

Remember that

A right triangle has a right angle and the other two angles are complementary

Let

------> one of the two angles that are complementary

------> the second of the two angles that are complementary

so

The measures of all angles are

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
