Hello!
Ignore the negative and solve the square root which is 13.
Add the negative with 13 you get -13
Special case is when it is square root of -169 then it will involved with i.
But for this question just solve it directly.
Have a great day!
Answer:
Below in bold.
Step-by-step explanation:
sin 66.4 = opposite side / hypotenuse
sin 66.4 = 21.3 / y
y = 21.3 / sin 66.4
y = 23.24.
tan 66.4 = 21.3 / x
x = 21.3 / tan 66.4
x = 9.31.
Answer:
