Step-by-step explanation:
(a)
A =

units²
(b)
Using Pythagoras' identity in the right triangle
let hypotenuse be h , then
h² = (4
)² + (
)²
= 32 + 
=
+ 
=
( take the square root of both sides )
h =

← rationalise the denominator
h =

- <em><u>A. Draw a diameter of the circle. </u></em>
Explanation:
To<em> draw a square</em> you can <em>draw a circle</em> with a <em>compass</em> and then construct the inscribed square.
You can construct an inscribed square with a compass and a straightedge.
The <u>first step</u> is to draw the circle.
The <u>next</u> step is to <em>draw a diameter</em> (any line that passes through the center of the circle, which you marked when drew the circle). Hence, this is the correct answer to the queston, and it is described by the choice A.
After that, you will be able to draw the perpendicular bisector of the diameter. The two diameters drawn will mark four equidistant points on the circle which will be the four vertices of your square.
Finally, you just must join the adjacent vertices with the straightedge.
Answer:
Step-by-step eNow examine the right triangle on the left in the figure.
x%2F10=sin%2850%29, in reference to the 50 degree angle, hypotenuse is that slanted segment of 10 units, and "x" is the opposite side from the 50 degree angle.
You do 5*7=35 and then subtract 35-30 to get your answer 5 less species
