Fraction: least to greatest...<br><br> 2/3, 9/16, 0.52

KonstantinChe [14]

First of all, you have to change the numbers in to the same form so I am going to change it to percentage.
2/3 = 0.66
9/16 = 0.56 So= 0.52, 9/16, 2/3
0.52

Please help me with my math

Andre45 [30]

$\sf{\qquad\qquad\huge\underline{{\sf Answer}}}$

Let's solve for x and z ~

$\qquad \sf \dashrightarrow \: z + 68 = 180$

[ they form co - exterior angle pair ]

$\qquad \sf \dashrightarrow \: z = 180 - 68$

$\qquad \sf \dashrightarrow \: z = 112 \degree$

now, it's time for x :

First angle z is equal to its vertical opposite angle, and then that angle forms co - interior angle pair with (3x - 28)

$\qquad \sf \dashrightarrow \: 3x - 28 + 112 = 180$

$\qquad \sf \dashrightarrow \: 3x + 84 = 180$

$\qquad \sf \dashrightarrow \: 3x = 180 - 84$

$\qquad \sf \dashrightarrow \: 3x = 96$

$\qquad \sf \dashrightarrow \: x = 96 \div 3$

$\qquad \sf \dashrightarrow \: x = 32 \degree$

That's all... let me know if you have questions ~
