Step-by-step explanation:

The answer is b. an obtuse. This is because if it were a right-angled triangle, then 90 + 30 + 40 would equal 180 and it doesn't. It's obtuse because 30 + 40 = 70, and triangles have to add up to 180° so the last angle would need to be 110°, which is an obtuse angle. I hope this helps!

An angle smaller than 90° is gonna be a acute so your answer is gonna be acute

Answer:

x ≈ 73.3

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos39° = $\frac{adjacent}{hypotenuse}$ = $\frac{57}{x}$ ( multiply both sides by x )

x × cos39° = 57 ( divide both sides by cos39° )

x = $\frac{57}{cos39}$ ≈ 73.3 ( to the nearest tenth )
