Both angle A & B are supplementary. If angle A is x and angle B is 3x, then what is x equal to AND what does angle B equal?

ryzh [129]

Answer:

A= 45 degrees

And angle B= = 135 degrees

Step-by-step explanation:

Supplementary means that the sum of both angles is equal to 180 degrees.

< A= x

< B= 3x

<a+<B= 180

x+3x= 180

4x= 180

x= 180/4

x= 45

Therefore angle A= 45 degrees

And angle B= 3x= 3*45= 135 degrees

The perimeter of a rectangle is 64 feet. If one side of the rectangle has a length of 20 feet, how long is the other side?

Helga [31]

Answer:

other side is 12

Step-by-step explanation:

Givens

Perimeter = 64 feet

L = 20

Formula

P = 2L + 2w Substitute Givens

64 = 2*20 + 2w Combine

64 = 40 + 2w Subtract 40 from both sides

64-40 = 40-40+2w Combine

24 = 2w Divide both sides by 2

24/2=2w/2

12 = w

I need help, arithmetic sequences always mess me up

Jlenok [28]

Answer:

$a_{45}=399$ is the required term.

Step-by-step explanation:

We have been given an arithmetic sequence where we have a common difference which is: $d=a_2-a_1$

$d=12-3=9$

We will use the formula to find the required term:

$a_n=a+(n-1)d$

where, a is first term which is 3 and d is the common difference which is 9

and n =45 which we require to find.

$a_{45}=3+(45-1)(9)$

$a_{45}=3+396$

$a_{45}=399$ .
