Find the value of x and the measure of the angle labeled 2xº

Mathematics
1 answer:
Doss [256]3 years ago

Answer: Option B (2x=28°, x=14°)

Step-by-step explanation:  2x+44° = 72°

<u><em>Let the point of intersection be O</em></u>

∠O = 180° - (28°+44°)

180°-72° = 108°

∴ As we know that 2x+44=72°

2x= 72-44

2x=28°

∴x=28/2 = 14°

Therefore the correct answer is Option B (2x=28°, x=14°)

Only 4 b and c please
Artyom0805 [142]

Answer:

a) 2L + 2W = 42

b) L = 2W + 3

c) The system is :

2L + 2W = 42

L - 2W = 3

( add the two equations )

3L + (2w - 2w) = 45

3L = 45

L = 45/3

L = 15 ( Length )

L - 2W = 3

15 - 2W = 3

2W = 15 - 3

W = 12/2

W = 6

Can someone smart help me with this question plz:)

Answer:

K = 50

L = 90

KML = 40

LMN = 140

Step-by-step explanation:

The sum of the angles in a triangle will always be 180 degrees, and in the triangle pictured, we know the value of each angle. We can say that

5x + 4x + 9x = 180

18x = 180

x = 10

Now that we know the value of x, we can figure out the value of the angles.

K = 5x = 50

L = 9x = 90

KML = 4x = 40

A straight line is 180 degrees, so to find angle KMN, you have to subtract KML (4x) from 180

180 - 4x = 180 - 40 = 140
