Answer:

$x=19$

Step-by-step explanation:

$We\ are\ given\ that,\\Line\ YZ\ ||\ ZW\\\angle XYM=90\\Hence,\\Line\ Segment\ XY\ being\ the\ transversal,\ cuts\ YZ\ and\ XW.\\Hence,\\We\ know\ that\\The\ set\ of\ co-interior\ angles [Interior\ angles\ on\ the\ same\ side\\ of the\ transversal]\ are\ supplementary.\\Hence,\\Here,\\The\ pair\ of\ co-interior\ angles\ formed\ are\ \angle XYZ\ and\ \angle YXW.\\Hence,\ they\ are\ supplementary\ too.\\Hence,\\\angle XYZ\ + \angle YXW= 180\\Hence, by\ substituting\ XYZ=90+2x,\angle YXW=3x-5$ $90+2x+(3x-5)=180\\85+5x=180\\5x=180-85\\5x=95\\x=19$

Solve for X please help

lbvjy [14]

Answer:

71 degrees

Step-by-step explanation:

Sum of three angles of triangle=180

Let's find the third angle

73+36=109

180-109=71

Vertical angles are congruent so x= angle 3

So x is 71 degrees

PLEASE HELP (100PTS)

Step2247 [10]

Answer:

x = 6

Step-by-step explanation:

• ∠THX and ∠XHV have a common side HX and a common vertex H

This means they are two adjacent angles.

Then

m∠THX + m∠XHV = m∠THV

Then

53 + 12x−9 = 16x + 20

<u>Solving the equation</u>:

53 + 12x−9 = 16x + 20

⇔ (53 − 9) + 12x = 16x + 20

⇔ 44 = 16x - 12x+ 20

⇔ 44 - 20 = 4x

⇔ 24 = 4x

$\Longleftrightarrow x = \frac{24}{4} =6$
