Step-by-step explanation:
To find : What is a irrational number between 12.1 and 12.2 ?
Solution :
An irrational number is defined as the number written in form or in proper fraction where p and q are integers and q is non-zero.
An irrational numbers are non-terminating and non-repeating.
So, An irrational number between 12.1 and 12.2 is any number which is non-terminating and non-repeating there are so many in between.
Let's take, 12.1243536859......
Therefore, The required irrational number between 12.1 and 12.2 is 12.1243536859......

Answer:
m∠A=90°, m∠B=60°, m∠C=30°
Step-by-step explanation:
step 1
Verify if the triangle ABC is a right triangle
Applying the Pythagoras theorem
----> is true
therefore
Is a right triangle
m∠A=90°
Find the measure of angle C
sin(C)=AB/BC
substitute
sin(C)=6/12=1/2
so
m∠C=30°
Find the measure of angle B
we know that
m∠C+m∠B=90°------> by complementary angles
so
m∠B=90°-30°=60°
