Answer:
c = sqrt(106)
Step-by-step explanation:
Since this is aright triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
5^2 + 9^2 = c^2
25 +81 = c^2
106 = c^2
Taking the square root of each side
sqrt(106) = sqrt(c^2)
c = sqrt(106)
The missing number to find the mean of 12 is 9.
Answer:
J.)
Step-by-step explanation:
Answer:
y=3.65
X=11.85
Step-by-step explanation:
sin(60)=y/12
sin(60)×12=y
y=3.65
sin(30)=X/12
sin(30)×12=X
X=11.85
