What is the measure of angle B in the triangle?<br>will give brainliest
spayn [35]
The angles of a triangle always add up to 180°.

120 + x + 16 + x = 180

Add up the values.

136 + 2x = 180

Subtract 136 from both sides.

2x = 44

Divide both sides by 2.

x = 22

The perimeter of a rectangle is 48 m. The area of the rectangle is 128 square meters. Find the dimensions of the rectangle.
Andreas93 [3]

Answer:

l = 16, w = 8

Step-by-step explanation:

Let l = length

Let w = width

Area = w * l

128 = w * l

w  = 128/l

Perimeter = 2w + 2l

48 = 2w + 2l

48 = 2(128/l) +2l

48 = 256/l +2l

Multiply everything by l

48l = 256 + 2l^2

l^2 + 128 = 24l

l^2 + 128 -24l = 0

(l-16)(l-8)= 0

L = 16

L = 8

If you try them out, and test it, l = 16 would work:

2(16) + 256/16 = 48

32 + 16 =48

16 * 128/16 = 128

16 * 8= 128

128 = 128

Since I'm not sure if you are in advanced math or not, I will do it simple with guess and check

Explain how the identity property in the problem, 2/3 (1) = 1 (2/3) = 2/3, is the same with any rational number. ANSWER FAST PLE
Morgarella [4.7K]
First of all, the identity property of multiplication (which is what this is I'm assuming) is that the number 1 multiplied by any other number is that number itself. (An example would be 2 multiplied by 1, which would be two) So in this problem, this rule applies too, since 2/3 multiplied by 1 would be 2/3!

Hope this helped :)
