Question

please anwer it step by step​

Answer 1

Step-by-step explanation:

We know that it is a straight line

=> <WZX + <WZY = 180° (Linear Pair )

=> 3x +20° +2x-15°=180°

=>3x+2x+20°-15=180°

=>5x+5=180°

=>5x=180-5

=>x=175/5

=>x=35

Answer 2

Answer:

Angle WZX = 125°

Angle WZY = 55°

Step-by-step explanation:

Angle WZX + Angle WZY = 180° [Because Line XY is a Straight Line/Angles in a straight line add up to 180°]

=> (3$x$ + 20°) + (2$x$ - 15°) = 180° [You should always give brackets for your own understanding]

=> 3$x$ + 20° + 2$x$ - 15° = 180° [Now, remove the brackets / You can also start writing from this step if you want]

=> 3$x$ + 2$x$ + 20° - 15° = 180° [Now, we solve (I hope you know how to solve it)]

=> 5$x$ + 5° = 180° [Solved]

=> 5$x$ = 180° - 5 [Now, we need to find out $x$]

=> $x$ = 175° ÷ 5

=> $x$ = 35 [We have found out the value of $x$]

Now, we find the measures by putting the value of x

3$x$ + 20 (Angle WZX) = 3 x 35 + 20 = 105 + 20 = 125°

2$x$ - 15 (Angle WZY) = 2 x 35 - 15 = 70 - 15 = 55°

There you go, the full explanation. I know that this will help you, can you also help me by marking my answer as brainliest?
