(Originais Teachy 2023) - Question Medium of Math

During a Mathematics class, the teacher drew a right triangle ABC on the board, where angle ABC is right and angles BAC and ACB are respectively 30º and 60º. The teacher then asked the students about the measurements of the sides of the triangle, considering that side AC (adjacent to the 30º angle) has a length of 5 cm. Based on this information, what is the length of side AB (opposite to the 30º angle) and the length of the hypotenuse BC?
a.
AB = 5 cm, BC = 10 cm
b.
AB = 10 cm, BC = 5 cm
c.
AB = 7.5 cm, BC = 12.5 cm
d.
AB = 6 cm, BC = 8 cm
e.
AB = 4 cm, BC = 6 cm

Question 1:

Medium

João found a right triangle in his geometry book where one of the acute angles measures 60º and the side opposite to this angle has a length of 3 cm. He was curious to know the length of the other side adjacent to the 60º angle, so he decided to calculate it using the basic trigonometric functions of sine, cosine, and tangent. What is the approximate length of the side that João wants to find?

Question 2:

João and Maria planted seeds in a garden and want to adjust the position of a sprinkler so that it waters the area correctly. They measured the distance of 10 m from the base of the sprinkler to the area that needs to be watered. Knowing that the height between the base of the sprinkler and the area to be watered forms an angle of 30º, what is the approximate height of the sprinkler relative to the ground?
