Look at the triangle: a right angle triangle is shown with hypotenuse equal to 17 centimeters. an acute angle of the triangle is labeled as x degrees. the side adjacent to the acute angle has length 15 centimeters and the side opposite to the acute angle has length 8 centimeters. what is the value of cos x°?

Step-by-step explanation:

Refer the attached figure

Hypotenuse = AC = 17 cm

An acute angle of the triangle is labeled as x degrees.i.e.∠ACB = x

The side adjacent to the acute angle has length 15 centimeters i.e. BC = 15 cm

The side opposite to the acute angle has length 8 centimeters.i.e. AB = 8 cm

Now we will use trigonometric ratio

So,

Hence the value of cos x° is

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
