Answer:
The graph is a solid line, and the shading is above the line.
Step-by-step explanation:
Given

Required
Describe the graph of the inequality
We have:

Subtract x from both sides

The sign
implies that the graph has a solid line
The sign
which means greater than or greater also implies that the upper region is shaded
Answer:
The base angles measure 78.46 degrees to the nearest hundredth.
Step-by-step explanation:
Applying the Cosine Rule:
10^2 = 10^2 + 4^2 - 2.4.10cosX where X is a base angle.
cos X = (100 - 100 - 16)/ (-80)
cos X = -16/-80
cos X = 0.2
X = 78.463 degrees
Answer:
C. 36.
Step-by-step explanation:
Answer:

Step-by-step explanation:
we know that
The sides of a rhombus are all congruent and the diagonals are perpendicular bisectors of each other
so
Applying the Pythagorean Theorem

where
c is the length side of the rhombus
a and b are the semi-diagonals
we have

substitute the values



To find out the perimeter of the rhombus multiply the length side by 4
