Answer:
yes , 33^2 + 56^2 = 65^2 and obtuse
Step-by-step explanation:
Question 3
make use of the Pythagoras theorem
which is :
c^2 = a^2 + b^2
where c is the hypotenuse.
now put the values in the equation
65^2 = 56^2 + 33 ^2
the answer is :
yes , 33^2 + 56^2 = 65^2
Question 4
note if :
c^2 = a^2 + b^2 ----------- right
c^2 < a^2 + b^2------------ acute
c^2 > a^2 + b^2------------- obtuse
hence :
16 + 30 > 38
therefore its : obtuse
