Write the following equation in standard form.
10x = -3y + 15

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

by definition every angles supplementary opposite by vertex are congruent

your answer is vertical angles!

step-by-step explanation:

a)  

step-by-step explanation:

we have to remove the roots and then apply exponential formula.

given,

we know,

so, we get

hence the answer is-
