The interior angles formed by the sides of a pentagon have measures that sum to 540°. What is the measure of angle B?
patriot [66]

Answer:

m∠B = 110°

Step-by-step explanation:

We know that,

The sum of the measures of the angles in a pentagon is 540°.

So, we get,

130 + (x-5) + (x+30) + 75 + (x-35) = 540

i.e. 3x + (130+30+75) - (5+35) = 540

i.e. 3x + 235 - 40 = 540

i.e. 3x + 195 = 540

i.e. 3x = 540 - 195

i.e. 3x = 345

i.e. x= 115°

Now, as m∠B = (x-5)° = (115-5)° = 110°

Hence, the measure of angle B is 110°.

Step-by-step explanation:

We understand rating as frequency or speed of doing something per time (seconds mainly)

{ \green{ \tt{rate = \frac{item \: quantity}{time}  }}} \\

Let's find rate in terms of seconds (words per second)

{ \rm{rate =  \frac{34 \: words}{ (\frac{1}{2} \times 60)  \: seconds} }} \\  \\ { \rm{rate =  \frac{34}{30} }} \\  \\ { \rm{rate = 1.133 \:  \: words \: per \: second}}
