Find the value of y in the rhombus below

All of a "rhombus's" sides are equal so if it states " one side is 30*" then all 4 sides are 30* .

If they are asking for the inside (perimeter) than you would have to divide 30* by 4 which leaves you with 7.5 .

To check your answer complete 7.5 x 4 and you'd get 30 .

(PLEASE MARK BRAINLIEST) :)

Is the given value a solution to the equation? 4(n) - 3 = -2(n) + 9 n=2

nlexa [21]

Answer:

Yes!

The solution to the equation is n = 2

Step-by-step explanation:

Given the equation

$4\left(n\right)-3=-2\left(n\right)+9$

remove the parentheses

$4n-3=-2n+9$

Add 3 to both sides

$4n-3+3=-2n+9+3$

Simplify

$4n=-2n+12$

Add 2n to both sides

$4n+2n=-2n+12+2n$

Simplify

$6n=12$

Divide both sides by 6

$\frac{6n}{6}=\frac{12}{6}$

Simplify

$n=2$

Therefore, the value of n = 2.

Hence,

Yes!

The solution to the equation is n = 2

76° x 135° 810 X = X= y=

enot [183]

Answer:

x = 68º

Step-by-step explanation:

This trapezoid is a quadrilateral. All degrees in a quadrilateral have to add up to 360º.

76º + 135º + 81º + xº = 360º

292º + xº = 360º

xº = 360º - 292º

xº = 68º

If mZ1= 140, what is m_3? 900 500 1300 400

zhuklara [117]

Answer:

∠ 3 = 50°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ 1 is an exterior angle of the triangle, so

90° + ∠ 3 = ∠ 1

90° + ∠ 3 = 140° ( subtract 90° from both sides )

∠ 3 = 50°
