Answer: 63 degrees.

Step-by-step explanation:

Angles in a triangle add up to 180 degrees.

Therefore: 54 + y + y = 180

So 54 + 2y = 180

So 2y = 126

Therefore y = 63 degrees.

Need help with 73, 74, 75, & 76. Find the value of X.

bija089 [108]

Answer:

see explanation

Step-by-step explanation:

73.

18 = 3x $\sqrt{3}$ (divide both sides by 3 )

6 = x $\sqrt{3}$ ( multiply both sides by $\sqrt{3}$ )

6 $\sqrt{3}$ = 3x [ $\sqrt{3}$ × $\sqrt{3}$ = 3 ]

divide both sides by 3

x = 2 $\sqrt{3}$

74.

24 = 2x $\sqrt{2}$ ( divide both sides by 2 )

12 = x $\sqrt{2}$ ( multiply both sides by $\sqrt{2}$ )

12 $\sqrt{2}$ = 2x ( divide both sides by 2 )

x = 6 $\sqrt{2}$

75.

9 $\sqrt{2}$ × x = 18 $\sqrt{2}$ ( divide both sides by 9 $\sqrt{2}$ )

x = 2

76.

2 = x × $\frac{4}{\sqrt{3} }$ ( multiply both sides by $\sqrt{3}$ )

2 $\sqrt{3}$ = 4x ( divide both sides by 4 )

x = $\frac{\sqrt{3} }{2}$
