The product of two numbers is 5070 and their LCM is 390 find the GCD of two numbers

LCM *GCD = Product of two numbers

390*GCD = 5070

GCD = 5070/390

GCD = 13

Hope this helps :)

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'.

it would open into a square depending on the type of envelope i’m not sure about the second part
