Answer:
5
Step-by-step explanation:
First do substitution,
Which means |(4)-3|+4
Therefore 1+4=5
Two triangles: left triangle with y degrees and 40 degrees and right triangle with x degrees.
- 40 degrees from the left triangle, when adding with the unknown angle of the right triangle, is equal to 180 degrees.
- Adding left triangle's (third) undetermined angle and x degrees angle (the other same angle), is equal to 90 degrees.
- The right triangle is an isosceles triangle, meaning two equal angles, and one of them is x degrees. Thus, the other same angle is also x degrees.
----------------------------------------------------------------------------------------------------------
1) Subtract 180 - 40 = 140 degrees. 140 degrees is the unknown angle of right triangle.
2) 140 + x + x = 180 (equation)
- 140 + 2x = 180
- 2x = 180 - 140
- 2x = 40
- x degrees = 20 degrees
ANSWER: x = 20 DEGREES
----------------------------------------------------------------------------------------------------------
1) With knowledge of x degrees being 20 degrees, the other same angle is 20 degrees, too.
2) Subtract 90 - 20 = 70 degrees. 70 degrees is the (third) undetermined angle
of left triangle.
2) 70 + 40 + y = 180
- 110 + y = 180
- y = 180 - 110
- y = 70 degrees
ANSWER: y = 70 DEGREES

Answer:
Step-by-step explanation:
A histogram displays frequencies of ranges; for example, in the given picture, in the range 
(including zero, excluding two), there are zero values.
To find the number of values below 10, we can look at each range individually:
Adding these frequencies up will give us the number of values below 10:
