SBC is an isosceles triangle with main vertex S.

stira [4]

Answer + Step-by-step explanation:

1) D be the symmetric of B with respect to C then CD = BC

A the symmetric of C with respect to B then AB = BC

We obtain :

CD = BC

AB = BC

Then AB = CD

2) m∠SBA = 180 - SBC = 180 - SCB = m∠SCD

3) we have :

BA = CD

BS = CS

m∠SBA = m∠SCD

Then

the triangles SBA and SCD are congruent

the triangles SBA and SCD are congruent Then SA = SD

Therefore SAD is an isosceles triangle.

I'm really confused on this one please answer !!!!!!!

Sedbober [7]

The formula for finding the area of a rug: $A = s^2$

Plugging in the values we know, we can solve for s.

$79 = s^2$

Take the square root of both sides.

$\sqrt{79} = s$

$\sqrt{79}$ is approximately equal to 8.89

So, 8.89 feet is the answer.
