Answer:
z=40 degrees
x=90 degrees
y=40 degrees
Step-by-step explanation:
To solve z you know that 50+90+z= 180 degrees. So z equals 40. To solve x you subtract 90 from 180 to get 90 degrees. To solve you add 50+x+y. You know that x= 90. You would add the angles together to get 180 degrees. 50+90=140 and 180-140 equals 40. Sorry if i'm wrong.
Answer:
Exponential form: y = x^½
Step-by-step explanation:
Given

Required:
The exponential form
To convert to an exponential function, we have to take exponents of both sides using the base of the logarithm function.
This gives us

Since the base of the exponential function and the logarithm is the same (x), they'll cancel out one another
This leaves us with

Hence, the exponential form of the expression
is 
We are simplifying this so they are easier to add in your head.
87+33 is easier math to do in your head
so our new estimated number would be 120
