In a rhombus, the diagonals bisect the opposite angles, and opposite angles are congruent.

Let's say angle 1 is x. The interior angles of a quadrilateral add up to 360°, so

30+30+30+30+2x=360

2x=240

x=120

angle 1 is 120°.

The length of a rectangle is five times its width.

Marizza181 [45]

ANSWER

96 yd

EXPLANATION

Let the width of the rectangle be w, then, the length of the rectangle will be:

$l = 5w$

The area of a rectangle is calculated using the formula:

$Area=l \times w$

$Area=5w \times w$

$Area=5 {w}^{2}$

It was given that, the area of the rectangle is 320yd²

$320=5 {w}^{2}$

Divide both sides by 5.

$64 = {w}^{2}$

Take square root of both sides to get:

$w = 8yd$

This means the length is

$l = 5 \times 8 = 40yd$

The perimeter of a rectangle is given by:

P=2(w+l)

We plug in the values to get:

$P=2(40 + 8) = 2 \times 48 = 96yd$

The perimeter is 96yd

One leg of a right triangular piece of land has a length of 24 yards. They hypotenuse has a length of 74 yards. The other leg ha

anastassius [24]

Solutions

To solve this problem we have to use the Pythagorean theorem. You can only use the Pythagorean theorem in Right Triangles. The longest side of the triangle is called the "hypotenuse". C² is the longest side so it is the hypotenuse . To calculate c² we have to do α² + β² = c².

Given

One leg of a right triangular piece of land has a length of 24 yards. They hypotenuse has a length of 74 yards. The other leg has a length of 10x yards.

First leg (24 yards) would be α

Second leg would be β

Hypotenuse (74 yards) would be c

Now we have points α β c.

a² (24) + β² ( x ) = c² (74)

Calculations

c² = α² + β²

74² = 24²+ β²

5476 = 576 + β²

5476 - 576 = β²
 
4900 = β²

→√4900
 
β = 70 yards

70 = 10x

x = 70÷10 = 7 yards

The second leg = 7 yards
