Step-by-step explanation:

A + 32 + 45 = 180 (why? Sum inside angles = 180 degrees. Proof? If you want learning proof, I show you)

A = 103

Answer:

Step-by-step explanation:

A + 32° + 45° = 180°

A + 77° = 180°

A = 180° - 77°

A = 103°

I hope I've helped you.

Find the area of following rhombuses. Round your answers to the nearest tenth if necessary.

Answer:

$Area =55.4ft^2$

Step-by-step explanation:

Given

The attached rhombus

Required

The area

First, calculate the length of half the vertical diagonal (x).

Length x is represented as the adjacent to 60 degrees

So, we have:

$\tan(60) = \frac{4\sqrt 3}{x}$

Solve for x

$x = \frac{4\sqrt 3}{\tan(60)}$

$\tan(60) = \sqrt 3$

So:

$x = \frac{4\sqrt 3}{\sqrt 3}$

$x = 4$

At this point, we have established that the rhombus is made up 4 triangles of the following dimensions

$Base = 4\sqrt 3$

$Height = 4$

So, the area of the rhombus is 4 times the area of 1 triangle

$Area = 4 * \frac{1}{2} * Base * Height$

$Area = 4 * \frac{1}{2} * 4\sqrt 3 * 4$

$Area =2 * 4\sqrt 3 * 4$

$Area =55.4ft^2$
