How many radians does the minute hand of a clock rotate through over half an hour? How many degrees?
Ivanshal [37]

Answer:

So minute hand will rotate \pi radian in half an hour

Step-by-step explanation:

In one hour minute hand of clock rotate about 360°

So in half an hour minute hand clock rotate \frac{360}{2}=180^{\circ}

We have to find how many minute hand rotate in radian

For conversion of degree to radian we have to multiply with \frac{\pi }{180}

So 180^{\circ}=180\times \frac{\pi}{180 }=\pi radian

So minute hand will rotate \pi radian in half an hour

Pls help me answer this question and plsss do not send link
Sever21 [200]

Answer:

x=124.75

Step-by-step explanation:

Sum of angles of a triangle=180°

(x-40)+(x-20)+(1/2- 10)=180°

(x-40)+(x-20)+(−9.5)=180°

x-40+x-20−9.5=180°

x+x-40-20-9.5=180°

2x−69.5=180°

2x=180°+69.5

2x=249.5

2x/2=249.5/2

x=124.75
