Answer:

the total area of the rhombus is 80 units².

Step-by-step explanation:

If we draw a horiz. line through the vertices (-1, 1) and (9, 1), we create a triangle with those points and (4, 9) as vertices. Thus, the base of this triangle is 9 - (-1), or 10, and the height is 9 - 1, or 8.

The area of this triangle is A = (1/2)(base)(height), or

A = (1/2)(10)(8) = 40 units². Since the lower triangle has the same area, the total area of the rhombus is 2(40 units²), or 80 units².

What is the arc measure of \stackrel{\LARGE{\frown}}{AC}

algol [13]

Answer:

72°

Step-by-step explanation:

Given that the radius(r) of the circle is 10 units and the length of arc ABC is 16π

The length of arc ABC = $\frac{\theta}{360}*2\pi r$

Where θ is the central angle in degrees.

Since the length of arc ABC is 16π,

$16\pi=\frac{\theta}{360}*2\pi r\\16\pi=\frac{\theta}{360}*2\pi *10\\\theta=\frac{16\pi *360}{2 \pi *10} \\\theta=288^0$

The angle in a circle = 360°, therefore:

Central angle for arc AB (θ) = 360 - Central angle for arc ABC = 360 - 288 = 72°

Therefore the arc measure of arc AB is 72°

Step-by-step explanation:

(think about it with a horizontal line between the two numbers)

When using fractions and whole numbers turn the whole numbers into fractions like ---> 3/1

and if their like 3 5/6 (for example) you would multiply the denominator by the whole number ---> 3*6=18 then add what's on the numerator with it. so 18+5=23 which would make it 23/6

Just some tips for making it easier!

Hope it helps! :)
