vladimir1956 [14]

Answer:

StartFraction StartRoot 3 EndRoot Over 3 EndFraction

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

we know that

In the right triangle XYZ

cos(Y)=\frac{ZY}{XY} ---> adjacent side divided by the hypotenuse

substitute the values

cos(30\°)=\frac{ZY}{4}

Remember that

cos(30\°)=\frac{\sqrt{3}}{2}

so

substitute

\frac{\sqrt{3}}{2}=\frac{ZY}{4}

ZY=(4)\frac{\sqrt{3}}{2}

ZY=2\sqrt{3}\ units

step 2

sin(Y)=\frac{XZ}{XY} --> opposite side divided by the hypotenuse

substitute the values

sin(30\°)=\frac{XZ}{4}

Remember that

sin(30\°)=\frac{1}{2}

so

\frac{1}{2}=\frac{XZ}{4}

XZ=2\ units

step 3

tan(Y)=\frac{XZ}{ZY} --> opposite side divided by adjacent side

substitute the values

tan(Y)=\frac{2}{2\sqrt{3}}

tan(Y)=\frac{1}{\sqrt{3}}

Simplify

tan(Y)=\frac{\sqrt{3}}{3}

so

StartFraction StartRoot 3 EndRoot Over 3 EndFraction

6(−2g−1)=−(13g+2) Solve for g
san4es73 [151]

Answer:

The solution is g = 4

Step-by-step explanation:

* 6(-2g - 1) = -(13g + 2)

- We need to solve it to find the value of g

- Let us simplify each side and then solve the equation

∵ 6(-2g - 1) = (6)(-2g) - (6)(1)

∴ 6(-2g - 1) = -12g - 6

∴ The simplify of 6(-2g - 1) is -12g - 6 ⇒ (1)

∵ -(13g + 2) = -13g - 2

∴ The simplify of  -(13g + 2) is -13g - 2 ⇒ (2)

- Equate (1) and (2)

∴ -12g - 6 = -13g - 2

- Add 13g to both sides

∴ g - 6 = - 2

- Add 6 to both sides

∴ g = 4

* The solution is g = 4
