Answer:

|SU|=\sqrt{13}

Step-by-step explanation:

The given parallelogram has vertices R(1, -1), S(6, 1), T(8, 5), and U(3, 3) .

Recall the distance formula;

We use the distance formula to determine the length of the diagonals.

For diagonal R(1,-1) and T(8,5), We have;

|RT|=\sqrt{(8-1)^2+(5--1)^2}

|RT|=\sqrt{(7)^2+(6)^2}

|RT|=\sqrt{49+36}

|RT|=\sqrt{85}

For the diagonal S(6,1) U(3,3)

|SU|=\sqrt{(6-3)^2+(5-3)^2}

|SU|=\sqrt{(3)^2+(2)^2}

|SU|=\sqrt{9+4}

|SU|=\sqrt{13}

Therefore the shorter diagonal is:

|SU|=\sqrt{13}

The diameter of a circle is 8 feet. What is the angle measure of an arc a feet long?
fiasKO [112]

Answer:

Given: circle

diameter = 10 cm => radius (R) = 5 cm

Find: measure of angle bounding sector = 11 π sq. cm.

Plan: determine what part of the circle’s total area equals the sector’s area.

Total Area of Circle A = π R^2 = π 5^2 = 25 π sq. cm.

Therefore: Sector Area = 11 π cm^2/25 π cm^2 = 11/25

Since the sector is 11/25 th of the circles area, the sector angle will measure 11/25 th of the circle’s circumference. They are proportional.

C = 2 π R = 2 π (5) = 10 π cm

Sector Arc = measure of sector angle = 11/25 (10 π) =

22π/5 radians

Answer: Sector Arc = 22π/5 Radians

Solve the following question
Anna11 [10]

Answer:

they are 16 and 4

Step-by-step explanation:

We can call the numbers x and y and we can write:

x - y = 12

x + y = 20

Adding these equations gives us 2x = 32 which means x = 16 and substituting this value into the first equation gives us y = 4.
