Triangle abc is a right triangle and cos(22.6o)=startfraction b over 13 endfraction. solve for b and round to the nearest whole number. triangle a b c is shown. angle a c b is 90 degrees and angle c a b is 22.6 degrees. the length of hypotenuse a b is 13 centimeters, the length of a c is b, and the length of c b is a.

a = 5 and b = 12

Step-by-step explanation:

Step 1: Find angle B

Angle C = 90°

Angle A = 22.6°

Angle B = B

All angles in a triangle are equal to 180°.

Angle A + Angle B + Angle C = 180°

22.6 + 90 + B = 180°

B = 180 - 112.6

B = 67.4°

Step 2: Find the value of side AC 'b'

Hypotenuse = 13

Adjacent = b

Angle A = 22.6°

Cos (Angle) = Adjacent/Hypotenuse

Cos (22.6) = b/13

b = 12

Step 3: Find the value of side CB 'a'

Hypotenuse = 13

Opposite = a

Angle A = 22.6°

Sin (angle) = Opposite/Hypotenuse

Sin (22.6°) = a/13

a = 4.99 rounded off to 5

Therefore, the value of a=5 and b=12.

use this formula:

p(a\b) = p(a and b)/p(b).
