Ineed finding the answers to these asap. i’m failing geometry right now and desperately need to raise my grade. any is greatly appreciated!

omg we’re learning that too!!

Step-by-step explanation:

1- a+b

2- divide that by 2

3- then times by the height

E.g the first example in the photo

16+9= 25

25 divide by 2= 12.5

12.5 x 10= 125

I hope I helped and you got it!

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

step-by-step explanation:

b and c
