143.17 times 1.35 = 193.28
Answer:
x ≈ 13.5
Step-by-step explanation:
Using the sine rule in the triangle, then
=
( cross- multiply )
x × sin27° = 11 × sin34° ( divide both sides by sin27° )
x =
≈ 13.5 ( to the nearest tenth )

The diagonal splits the square into two right triangles. We can then use the Pythagorean theorem to find the length of the diagonal (the hypotenuse of the triangle):
12² + 12² = x²
144 + 144 = x²
288 = x²
Take the square root of both sides:
√288 = √x²
16.97 = x
17≈x
