Answer:
x = (+ - ) 9
Step-by-step explanation:
x^2 = 81
u know how u can sometimes cancel something out by doing the opposite.
This is one of those times as well. the opposite of ^2 = square root.
so if we take the square root of both sides, this will cancel out the^2 on the left side.
sqrt (x^2) = sqrt(81)
x = (+-) 9.....thats a positive and a negative sign...because the sqrt of 81 is both 9 and -9.
Either of two angles whose sum is 180 degrees
Answer:
4
Step-by-step explanation:
We know that all lengths in a rhombus are equal so we make the 2 equations equal to each other, then solve for x:
x=4
