Please help me with trigonometry
NeX [460]

Answer:

cos R = .38

Step-by-step explanation:

First you need to find the length of the hypotenuse.

Use a squared + b squared = c squared

100 + 576 = c squared

square root of 676 is 26

CosR is adjacent over hypotenuse.

Adjacent is 10

Hypotenuse is 26

10/26 = .38

kkurt [141]

Answer:

39.6 cm

Step-by-step explanation:

Applying

s = 2πrθ/360................ Equation 1

Where s = length of an arc or distance traveled by the minutes hand of the clock during the 42 munites, r = length of the minutes hand of the clock, θ = Angle traveled by the minute hand of the clock for every 42 minutes

From the question,

Given: r = 9 cm, θ = 252°

Constant: π = 22/7 = 3.14

Substitute these values into equation 1

s = (2×3.14×9×252)/360

s = 39.564

s = 39.6 cm
