If ABCD is a parallelogram find the value of unknow size​

Mathematics
1 answer:
Keith_Richards [23]3 years ago
5 0

Step-by-step explanation:

Hey, there!!

As it is a parallelogram, remember basic properties of parallelogram,

  • Their opposite sides are parallel and equal to eachother.
  • Their opposite angles are equal.
  • They have properties of parallel lines too.

Now, lets solve your question.

b = (7×10)°

Therefore, b= 70°.

now, (3x+10°)+b=180° { co- interior angle of a triangle sum is 180°}.

or, 3x= 180°-80°

or, x= 100°/3

Therefore, x= 33° { rounding off we get 33}.

w+ b =180°

w+70°=180° { coointerior angles are equal}.

Therefore, w =110°

Median = 75 because that is where the middle line of the box is.

First quartile = 70 because that is what the left edge of the box represents.

Third quartile = 85 because the right edge of the box indicates that.

Maximum = 100 because at the far right is the maximum data point of your data set.

The middle 50% of that data is between 70 and 85 because those are the values the box covers. It goes from the first quartile, 70, and stretches all the way to the third quartile 85.

the rectangular post shown at the right measures 2w-30 by w. the poster has an area of 5400 cm^2. what is The value of w ?
borishaifa [10]

Step-by-step explanation:

w(2w - 30) = 5400

2w²- 30w = 5400

2w² - 30w - 5400 = 0

(w - 60 ) ( w + 45 ) = 0

w= 60 w= - 45

only take the positive value

therefore w = 60
