WILL MARK BRAINLIEST <br>slove for the following variables

UkoKoshka [18]

Answer:

Step-by-step explanation:

All triangle must have angle values adding up to 180 degrees.First solve for y;

110+33+y=180

y=37 degrees

x is the opposite inverse angle of 33 degrees, it has an angle measure of 33 degrees.

z is equal to 110 degrees because it is opposite to that angle measure because all rhombi have 2 way symmetry.

A rectangle is 4.2 centimetres wide and each diagonal is 8.6 centimetres long. What is the measure of the angle between a diagon

CaHeK987 [17]

Answer:

$60.8^\circ$

Step-by-step explanation:

First, let's check side lengths.

Using the Pythagorean theorem we can find the length of the other side of the rectangle.

a^2 + b^2 = c^2

4.2^2 + b^2 = 8.6^2

b^2 = 56.32

b = 7.5

The other side of the rectangle measures 7.5 cm, so now we know that 4.2 cm is indeed the shorter side of the rectangle.

For the angle in question, the 4.2 cm side is the adjacent leg.

The diagonal of 8.6 cm is the hypotenuse.

The trig ratio that relates the adjacent leg to the hypotenuse is the cosine.

$\cos \alpha = \dfrac{adj}{hyp}$

$\cos \alpha = \dfrac{4.2~cm}{8.6~cm}$

$\alpha = \cos^{-1} \dfrac{4.2~cm}{8.6~cm}$

$\alpha = 60.8^\circ$

Answer: a) 92 yards, b) 29.29 yards and 672.99 sq. yd.

Step-by-step explanation:

Since we have given that

Area of square pen = 529 sq. yd

Let the length of each side be 'a'.

As we know the formula for "Area":

$Area=a^2\\\\529=a^2\\\\\sqrt{529}=a\\\\a=23\ yd$

So, the perimeter of the square pen is given by

$4\times s=4\times 23\\\\=92\ yd$

So, perimeter of square pen = Perimeter of round pen

$92=2\pi r\\\\92=2\times 3.14\times r\\\\\dfrac{92}{2}=3.14\times r\\\\\dfrac{46}{3.14}=r\\\\14.64=r$

So, the diameter of round pen is $2\times r=2\times 14.64=29.29\ yd$

And the area of round pen is

$\pi r^2\\\\=3.14\times (14.64)^2\\\\=672.99\ sq.\ yd$

Hence, a) 92 yards, b) 29.29 yards and 672.99 sq. yd.
