Answer:
Step-by-step explanation:
To solve, we need to take square root of both sides first:
Now we use the property of radical shown below to simplify square root of 28:
Property:
Now, we have:
Now we take 4 to the other side and isolate x:
first answer choice is right.
The answers are very hard to see
Answer:
50 degrees
Step-by-step explanation:
A whole line is 180 degrees.Subtract the known angle from 180 to find the missing angle,which is 50 degrees.
X = 7 / sin(45)
x = 7 / sqrt(2)/2
x = 7 sqrt(2)
