The sum of the angles of a triangle is 180°. If one angle of a triangle measures x and the second angle measures (5x +19)º

lapo4ka [179]

Answer:

third angle = (-6x + 161)°

Step-by-step explanation:

180° = (x)° + (5x + 19)° + third angle →

180° = (6x + 19)° + third angle →

180° – (6x + 19)° = (6x + 19)° + third angle – (6x + 19)° →

180° – (6x + 19)° = third angle →

180° + -(6x + 19)° = third angle →

180° + (-6x)° + (-19)° = third angle

180° – 6x° – 19° = third angle

(180° – 19°) – 6x° = third angle

161° – 6x° = third angle

third angle = 161 – 6x°

third angle = -6x° + 161°

third angle = (-6x + 161)°

Which expression is equivalent to<br> (X^1/4 y^16)^1/2?

lawyer [7]

Answer:

$x^{\frac{1}{8} } y^{8}$

Step-by-step explanation:

Given :

$(x^\frac{1}{4} y^{16} )^{1/2}$

Now,

$(x^\frac{1}{4} y^{16} )^{1/2}\\x^{\frac{1}{8} } y^{8}$

Therefore, expression is equivalent to $x^{\frac{1}{8} } y^{8}$

Answer:

x = 1.5 $\sqrt{3}$

Step-by-step explanation:

using the sine ratio in the right triangle and the exact value

sin60° = $\frac{\sqrt{3} }{2}$ , then

sin60° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{3}$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

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

x = 1.5 $\sqrt{3}$
