Step-by-step explanation:
Surds are irrational numbers expressed with respect to a square root. There are some basic rules required when dealing with surd.
Integers are numbers that do not have a decimal or fractional part i.e whole numbers. So, a simple expression that can be written as k square root 3 where k is an integer is .
So that,
= 
= 4

Answer:
<B = 70°
Step-by-step explanation:
First we need to find x, lets plugin these two equations.
2x - 30 = x + 20
Then find like terms
2x = x + 50 =
x = 50
Then we plugin 50 for x
2(50) - 30 =
100 - 30 = 70
<B = 70°
