Answer:

Step-by-step explanation:

x represents the hypotenuse of that right triangle. The reference angle is 52 and is opposite AB, the side which we need to find. The trig ratio that uses the hypotenuse and the side opposite the reference angle is the sin ratio, namely:

sin52=\frac{AB}{7.7} and

7,7sin52 = AB so

AB = 6.07 m

!!Help Me!!<br> Solve the rational equation:
nadya68 [22]
Least common denominator is (x-1)(x-2) = x²-3x+2.
2x(x-2)/((x-1)(x-2)) - (2x-5)/((x-1)(x-2)) = -3(x-1)/((x-1)(x-2))
2x(x-2) - (2x-5) = -3(x-1)
(2x²-4)-(2x-5) = -3x+1
2x²-2x+1 = -3x+1
2x²+x = 0
x(2x+1) = 0
x = 0,-½
