Answer:

x = 68°

Step-by-step explanation:

Let us solve the question

In the given figure

∵ The ray WD bisects ∠ZWN

→ That means it divides the angle into two equal angles, ∠ZWD and ∠DWN

∴ m∠ZWD = m∠DWN

∵ m∠ZWD = 5v - 7

∵ m∠DWN = 4v + 8

→ Equate the measures of the two angles

∴ 5v - 7 = 4v + 8

→ Add 7 to both sides

∵ 5v - 7 + 7 = 4v + 8 + 7

∴ 5v = 4v + 15

→ Subtract 4v from both sides

∵ 5v - 4v = 4v - 4v + 15

∴ v = 15

∵ x = m∠ZWD

∴ x = 5v - 7

→ Substitute v by 15

∵ x = 5(15) - 7

∴ x = 75 - 7

∴ x = 68°

A sign is being made from a rectangular board of wood that originally measures 36 inches by

lozanna [386]

<h3>Solution (a):</h3>

Area of rectangle = LB
=> Area of rectangle = 18 x 36
=> Area of rectangle = 648 in²

<h3></h3><h3>Solution (b):</h3>

<u>Since the two triangles are equal (as said in the question):</u>

=> Area of triangles: 2(1/2 x 6 x 18)
=> Area of triangles: 6 x 18
=> Area of triangles: 108 in²

<h3 /><h3>Solution (c):</h3>

<u>Subtract the area of the triangles from the area of the rectangle.</u>

648 - 108 = Area of trapezoid
=> 540 in² = Area of trapezoid

Make six prime numbers using the digits 1, 2, 3, 4, 5, 6, 7, 8, 9 once each.

lana [24]

Answer:

2, 3, 5, 7, 11, 13.

Step-by-step explanation:

A prime number is a number that you don't get a whole number when divided by 2 but you do get a whole number when divided by prime numbers such as 3,5,7,11... Basically a number with two factors, it can only be divided by 1 or themselves. for example:

9/2 = 4.5 (this is not a whole number so it might be a prime.

9/3 = 3 (it works when divided by a prime number.

another:

8/2 = 4 (it gives a whole number when divided by 2 therefor, it can't be a prime number.

Answering:

There are 6 prime numbers at the top^^^^.
