What is the sign of the product (-5)(-3)(-8)(-6)? a Positive, because the products (-5)(-3) and (-8)(-6) are negative, and the product of two negative numbers is positive
b Positive, because the products (-5)(-3) and (-8)(-6) are positive, and the product of two positive numbers is positive
c Negative, because the products (-5)(-3) and (-8)(-6) are negative, and the product of two negative numbers is negative
d Negative, because the products (-5)(-3) and (-8)(-6) are positive, and the product of two positive numbers is negative

A

Step-by-step explanation:

there all negavtive so they would equal a positive

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'.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
