Answer:

Step-by-step explanation:

21. 136° and b are supplementary, meaning they have a sum of 180°. This means that 136° + b = 180° → b = 44°.

22. Again, the angles are supplementary which means that 61° + b = 180° → b = 119°.

23. Again, they are supplementary which means that x - 22° + 135° = 180° → x + 113° = 180° → x = 67°.

24. I'm pretty sure you get the gist of this. 6x + 3° + 87° = 180° → 6x + 90° = 180° → 6x = 90° → x = 15°

Hope this helps!

State the value of 'x' in this equation, and explain why you know this to be true without doing any calculations. 5X=59

Zigmanuir [339]

The value of x in the equation is 59/5

<h3>How to solve for x?</h3>

The equation is given as:

5x = 59

Divide both sides by 5

x = 59/5

This means that the value of x in the equation is 59/5

To know if the value is accurate, we simply multiply 5 by 59/5 and we get 59 as in 5x = 59
