Answer:
D)99 degrees
Step-by-step explanation:
The answer is D. All the angles in any quadrilateral add up to 360 degrees. And since the figure is a paralledlogram, for each angle there is another angle with the same measurement. So 81 + 81 + x + x = 360 which gives us 162 + 2x = 360. If you solve for x you get 99 degrees.
Answer:
8t+4=76
Step-by-step explanation:
An equation needs an equals sign otherwise it is an expression
The sum of the interior angles of a triangle is 180 degrees. Therefore, if we add up all of these angles, they will equal 180.
82 + 55 + x = 180
137 + x = 180
x = 43 degrees

Answer:
11) mean=2 12) median=2 13)range =4
Step-by-step explanation:
11) the set is
0,0,1,1,1,2,2,2,2,2,3,3,3,4,4
so add all these which will give you 30 and then divide that by how many numbers are there in the set which there are 15, so 30 divided 15 =2
12) arrange numbers from smallest to largest and the number exactly in the middle is the median
13)biggest number-smallest number
Answer:
4 m.
Step-by-step explanation:
Length of ladder, L = 4.50 m
Base of ladder from the wall, B = x
Height of the wall, H = 2x
Using Pythagoras theorem




Height of the wall is equal to 2 x 2 = 4 m.
