Answer:
I could be mistaken but I believe that x= 42.5
Step-by-step explanation:
To find this, you solve for 4x+10=180.
This is because the total angle measure of line RD should be 180 degrees.
When you solve this equation, you get 42.5 for X
The answer is the option D because the formula is y upon x
How to find the mixed number to a fraction:
Let's take 3/2 for instance.
1) You will see how many times the denominator (bottom number) goes into the numerator (top number) in this case that is one time.
2) You will place that number (1) off to the side like so --> 1
3) Then you will see how many parts are left, in this case that is 1 and place that number over the original denominator like so: 1/2
4) Finally you will just combine to get your answer- 1 1/2

(-5+i)/2i
multiply by i/i
(-5+i) *i = -5i +i^2 = -5i -1
2i*i = 2i^2 = 2(-1) = -2
(-1-5i)/-2
1/2 +5/2 *i
