Of 81 square feet and a base length of 9 feet. What is the height of the parallelogram?
mote1985 [20]
Your answer would be 9 feet
81=area
9=base
_=height
and area is base x hight so you divide the base by the area so an equation would be 81=9x then you would flip it around so it would be 9÷81=x
x=9
Hope this helps!!

Answer:

C = 132°

Step-by-step explanation:

(5y + 28) = 12y

5y - 5y + 28 = 12y - 5y

28 = 7y

y = 4

12 (4)

= 48

48 + C = 180°

48 - 48 + C = 180 - 48

C = 132°

Why do diamonds form in lava tubes?
evablogger [386]
"Let There Be a Gas Phase"
There, a type of material called kimberlite magma causes the solid rock to break its way up from deeper into the mantle of Earth. The magma gathers fragments of rocks as it rises, like floodwaters gathering up silt and gravel. Diamonds are contained in some of these fragments.
