Answer:
C
Step-by-step explanation:
Okay! Time to use the Pythagoras theorem.
a^2 + b^2 = c^2
4^2 + 7^2 = x^2
16 + 49 = c^2
65 = c^2
Let's take the square root of both sides to get
c ~ 8.06
C
:)
89 squared minus 39 squared and the answer you get is what you put into the radical
Because of a linear pair then because of vertical angles and because all angles have to be 180 added up
It has already given you the answer.
