Answer:
The graph on the top right is the correct graph.
Step-by-step explanation:
Because the inequality is 
, we know that the circle has to be closed. This leaves us with only three graphs left. We also know that it includes everything, including the decimals in between the integers, not just the integers themselves. Therefore, the graph on the top right is the correct graph.
Answer:
-2
Step-by-step explanation:
Answer:
area= 1/2*(h*b) h- height, b- base
the triangle is isosceles (denoted by the 2 dashes on the sides of the triangle)
so they are equal in length
angles in triangle = 180
so 38+38=76
180-76=104
base=24
divide the triangle in the center
so now triangle 1(left) the base = 12
and triangle 2(right) the base = 12
use trigonometric ratios
in this we need to find the height
which is opposite of 38,
we already have the adjacent =12
so the ratio is Tan (Tangent Opposite/Adjacent)(TOA)
Tan38= (12/h)
multiply by h
h*Tan38=12
h=12/tan38 = 15.35929959
The value of x is given by the pythagoras theorem
X^2 = 17^2 - 15^2
X^2 = 289-225
X^2 = 64
X = sqrt64
X= 8cm
