Answer:

∠RVS = 154°
x = 12

Step-by-step explanation:

The diameter cuts the circle into parts that total 180° of arc.

RS +ST = 180°

RS = 180° -ST = 180° -26° = 154°

∠RVS = 154°

This value can be used to find x. Equating the angle measures, we have ...

RS = (15x -26)° = 154°

15x = 180 . . . . . divide by °, add 26

x = 180/15 . . . . divide by 15

x = 12

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
