H: hours
45h + 45 = 30h + 75
15h + 45 = 75
15h = 30
h = 2 hours

45 ( 2 ) + 45 = 30 ( 2 ) + 75
90 + 45 = 60 + 75
135 = 135

Therefore the awnser is 2 hours.

Given ∠A= 210° and ∠B= 4 radians, which angel is bigger? justify your response.
8090 [49]

Answer:

∠B

Step-by-step explanation:

To convert from radians to degrees, multiply the radians by 180°/π

⇒ ∠B = 4 × 180°/π

⇒ ∠B = 229.2° (nearest tenth)

As 229.2° > 210° then ∠B is bigger than ∠A

The length of a rectangle is 55 meters less than 44 times the width. if the perimeter is 150150 meters, find the length and the
MrRa [10]
They did not state exactly what the width or length is. So in this case, let's name the number of width to be x. And thus we can derive to the conclusion of,

Width : x
Length : x-44 (from the 1st sentence of question)
So, We all know that a rectangle has 2 Lengths and 2 widths. So we can derive the conclusion that,
2(x)+2(x-44)=150150
2x+2x-88=150150
4x-88= 150150
4x= 150150+88=150238
4x=150238
x= 150238÷4
=37559.5
