Use the relationship between the angles in the figure to answer the question. Which equation can be used to find the value of x?
Allushta [10]

Answer:

1. 52° + x° + 67° = 180°

2.  x° + 22° = 90°

Step-by-step explanation:

1. In the first figure,

Since the angles given are supplementary angles i.e. their sum is 180°

So, we get,

52° + x° + 67° = 180°

i.e. x° = 180° - 119°

i.e. x° = 61°

Thus, the expression to find the value of x is 52° + x° + 67° = 180°.

2. In the second figure,

Since the angles given are complementary angles i.e. their sum is 90°

This gives us,

x° + 22° = 90°

i.e. x° = 90° - 22°

i.e. x° = 68°

Hence, the expression to find the value of x is x° + 22° = 90°

Can someone please explain why x= -2! ASAP!!
bearhunter [10]
Because you add both negative x’s which is -2 and add the -6 in the right side so then it’s -2x=4
Divide and you get x=-2
