42
let the smallest even number be x, than the four even numbers are x, x+2, x+4, x+6, their sum is 180
x+x+2+x+4+x+6=180
4x+12=180
4x=168
x=42
the smallest even number is 42.
Answer: No it is not.
Step-by-step explanation: A rational number is a number that can easily be expressed as a fraction or decimal, and square root of 7 cannot be easily expressed.

I did it and it was right
Answer:
x ≈ 13.5
Step-by-step explanation:
Using the sine rule in the triangle, then
=
( cross- multiply )
x × sin27° = 11 × sin34° ( divide both sides by sin27° )
x =
≈ 13.5 ( to the nearest tenth )
The angle is a complementary angle so both angles add up to 90 degrees
Therefore set your equation equal to 90 to find angle of x
53+x=90
Subtract 53 from both sides
X= 37 degrees
