we know that
In a right triangle
Applying the Pythagorean Theorem
where
a and b are the legs of the triangle
c is the hypotenuse of the triangle
Step N
<u>Assume that the third side is a leg</u>
In this case we have
Solve for b
substitute the values
Step N
<u>Assume that the third side is the hypotenuse</u>
In this case we have
substitute the values
Step N
<u>Find the difference of the third sides</u>
therefore
<u>the answer is</u>
Answer:
Side D is 0.78 feet (to 2 s.f.)
Step-by-step explanation:
In the Scale Drawing, side D=24 centimeters
1 foot = 30.48cm
x foot = 24 cm
Therefore:
24 X 1 = 30.48 X x
x= 24/30.48 =0.7874 feet
Side D is 0.78 feet (to 2 s.f.)
If this is for E2020 the answer is
D)<span>No, his value of </span><span> should be positive because an even exponent indicates a positive value.
thats why it was wrong</span>
