Answer:
C
Step-by-step explanation:
Using the trigonometric identity
csc x = 
Given
sinΘ = - 0.4, then
cscΘ =
= - 2.5 → C
Answer:
a
Step-by-step explanation:
this is because it is right
X=2
So you solve for x by simplifying bath sides of the equation, then all you do is isolate the variables
Answer:
y ≥−3
Step-by-step explanation:
1 By inspecting the graph, the range is:
y\ge -3y≥−3
Done
Answer:
Step-by-step explanation:
Because midpoints were used to make similar triangles we can say
AC=2(DE)
5x+12=2(9x-20)
5x+12=18x-40
-13x+12=-40
-13x=-52
x=4
AC=5x+12
AC=5(4)+12
AC=20+12
AC=32
