Answer:

a) 14,1 cm

Step-by-step explanation:

If a circle passes through the vertices of a square then the diagonal of a square is a circle diameter.

We use Pytagoras Theorem to find out the length (L)  of the diagonal given that:

L²  =  (20)²  +  (20)²

L²  = 2* (20)²

L  = √2 * 20

L  = 1,4142* 20

L = 28,28 cm

L diagonal in the square is a diameter of the circle then radius of a circle is:

r = L/2   ⇒   r  = 28,28 /2   ⇒   r = 14,14 cm

True [87]

Answer:

tanC = 3/4

Step-by-step explanation:

by Pythagoras theorem first find the line DE =

36^{2}+DE^{2}=45^{2}

-> DE=27

then we know that tanθ=opposite/adjacent

so, 27/36 =tanC

simplified: tanC = 3/4
