The answer is below
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, scalene, equilateral, acute, obtuse and right angled triangle. A right angle triangle is a triangle with one angle being 90°.
Trigonometric ratios is used to show the relationship between the angles and sides of a right angled triangle. Examples are:
sinΘ = opposite/hypotenuse; cosΘ = adjacent/hypotenuse; tanΘ = opposite/adjacent
From the question:
cos(62) = AB/12
AB = 12 * cos(62)
AB = 5.6 cm
Answer:
c
Step-by-step explanation:
because it is the highest
They are similar. If two of the corresponding angles are the same, the third one is corresponding. If a triangle angles are, 60, 60, 60, that adds up to 180... but if a triangle's angles are ,60 ,60, 50, that is impossible. All angle measures must add up to 180*.
