Answer:

D) 151°

Step-by-step explanation:

First we recall the fact that angles in a triangle add to 180°

So this means that we can find the angle above 's'

61° + 90° + ? = 180°

151° + ? = 180°

? = 29°

So the angles above 's' is 29°

Then we recall the fact that angles on a straight line add to 180°

So this means that

s + 29° = 180°

s = 151°

Answer:

Hi!!!

Your answer is s = 151°.

Remember s is the value that we are looking for.

And x is other values that are not shown in the picture.

You also must remember that all angles add up to 180.

What you do now is add.

61° + 90° + x = 180°

151° + x = 180°

x = 29°

Now, we think. What plus 29 would give you 180. So, lets subtract.

:)

180°  - 29° = s

s = 151

So, that means s = 151°. So the missing angle is  151°.

Hope this helps, have a great day, Stay Safe, and Positive.
