answer is 6
Answer:
$12.6
Step-by-step explanation:
9/5=x/7
1.8=x/7
*7 *7
12.6=x
I think the question is missing some details. I found a similar question with an image as i attached in this question.
From this image, it its clear that m1, m2 and m3 refers to the angles in the middle of the rhombus
Answer:
x = 9
y = 81
z = 5
Step-by-step explanation:
Note that in rhombus, all sides are the same. If the diagonal lines are made, it will create 4 division of angles of 90 degrees.
Therefore m1 = m2 = m3 = 90 degrees
m1 = 10x and m1 =90
So, 10x = 90. Rearrange it to get x = 90/10 = 9
x = 9
m2 = x + y and m2 = 90
So, x + y = 90
9 + y = 90
y = 90 - 9 = 81
m3 = 18z and m3 = 90
So, 18z = 90
z = 90/18 = 5
2x+31=3x+5
2x-3x=5-31
-1x=-26
So x=26
√18 = √(9*2) = √9 *√2 = 3 * √2 = 3 √2. (Which is C)
