Find the measure of the missing angles.
X=
Y=
Z=

Answers

Answer:

X= 41

Y= 90

Z= 41

Step-by-step explanation:

X=Z

Y+49=139

Z+Y+49=180

X+139=180

139+49+X+Z+Y=180

These we know because of the placement of the angles.

Using this information, we can solve this in numerous ways. I'm going to solve it using one of them. Making both sides equal to 180 and then checking my work by adding all of the numbers I get together to make sure that they equal 360.

X+139=180

X=41

X=Z.

49+Z+Y=180

49+41+Y=180

90+Y=180

Y=90

Thus,

X= 41

Y= 90

Z= 41

To check, let's add them all together.

41+90+41+139+49=

360

This is correct!

X=41
Y=90
Z=41

plz help me i really need help like really plz help asap asap ASAP PLZ HELP ME

Hey there!

The sum of angles in a triangle ALWAYS adds up to 180 degrees.

So, we can set the expressions equal to eachother, and solve for x:

6x - 5 + x + 8 + 2x - 3 = 180

Add like terms:

9x = 180

Divide both sides by 9:

x = 20

Now, we plug x into the expressions to find their angle values:

m∠J = x + 8

m∠J = 20 + 8

m∠J = 28

m∠K = 6x - 5

m∠K = 6(20) - 5

m∠K = 120 - 5

m∠K = 115

m∠L = 2x - 3

m∠L = 2(20) - 3

m∠L = 40 - 3

m∠L = 37

Have a super awesome day! :)
