Answer:

72 $\sqrt{3}$

Step-by-step explanation:

The area (A) of a rhombus is calculated as

A = $\frac{1}{2}$ × d₁ × d₂ (d₁ and d₂ are the diagonals )

The diagonals bisect each other at right angles

d₁ = 2 × 6 = 12

Use the tangent ration in the upper left right triangle and the exact value

tan60° = $\sqrt{3}$

tan60° = $\frac{opposite}{adjacent}$ = $\frac{opp}{6}$ = $\sqrt{3}$ ( multiply both sides by 6 )

opp = 6 $\sqrt{3}$ , then

d₂ = 2 × 6 $\sqrt{3}$ = 12 $\sqrt{3}$

Thus

A = $\frac{1}{2}$ × 12 × 12 $\sqrt{3}$ = 6 × 12 $\sqrt{3}$ = 72 $\sqrt{3}$

Ghella [55]

Y=3x-4
This affects the previous line because now the slope is a positive which completely turns it around. and the Y intercept is now on the opposite side of the X axis

C. Line m is a perpendicular<br> bisector. If EG=12 and FG=5,<br> of then how long is:

strojnjashka [21]

Answer:

$EF = 13$

$GH = 5$

$EH = 13$

Step-by-step explanation:

Given

The attached figure

$EG = 12$

$FG = 5$

Solving (a): EF

Since m is a perpendicular bisector, then <EGF and <EGH are right-angled.

So, EF will be calculated using Pythagoras theorem which states:

$EF^2 = EG^2 + FG^2$

$EF^2 = 12^2 + 5^2$

$EF^2 = 144 + 25$

$EF^2 = 169$

Take the positive square roots of both sides

$EF = \sqrt{169$

$EF = 13$

Solving (b): GH

Since m is a perpendicular bisector, then GH = FG

$FG = 5$

$GH = FG$

$GH = 5$

Solving (c): EH

Since m is a perpendicular bisector, then EH = EF

$EF = 13$

$EH = EF$

$EH = 13$

I would say based on Lincoln's success and that Lincoln helped inspire Martin. Lincoln won the Civil War which helped open the minds of other people who were pro-slavery so that's what I mean about the success.
