How would I do this and work it out ? Only 15-17 please help me !!

u need to find the square root, I hope u can understand I'm really bad at explaining

Step-by-step explanation:

so the symbols around the number means square root of...I'll give u an example

square root of 4

so 2×2=4, the square root has to be the same number like 2 and 2

if u need to find the square root u can multiply the numbers such as..

1x1

2x2

3x3

4x4

5x5

6x6

7x7

8x8

9x8 etc.

unlit u find the square root of any number. if u find the closest number but it's not quite the square root u can use decimals as well!

as I said I am terrible at explaining so let me know if u need any clarification

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
