Answer:
Step-by-step explanation:
lets find out 9 times ? = 72
to do this, simply divide: 72/9 = 8
Since the end product is a negative and the factor is a negative, 8 will be a positive number
-9 times 8 equals -72
hope this helped ;)
Answer:
x ≈ 11.5° or 168.5°
Step-by-step explanation:
csc² x − 5 csc x = 0
Factor:
csc x (csc x − 5) = 0
Set each factor to 0 and solve:
csc x = 0
sin x = undefined
no solution
csc x − 5 = 0
csc x = 5
sin x = 1/5
x = arcsin(1/5)
x ≈ 11.5° or 168.5°
Answer: the triangles are congruent
Step-by-step explanation: if u add up all the angles u get 180 so all angles are congruent
Answer:
m=
Step-by-step explanation:
Gladly!
To find the slope, we need to find the change between <em>point a</em> and <em>point b</em>
With the difference between x1 and x2 being 4, and the difference between y1 and y2 being 1, we get a fraction that looks like this,
This right here is the slope of the line. Hope this helps!
Answer:
the length is 8ft
the width is 3ft
Step-by-step explanation:
Step one:
given
perimter= 22ft
let the length be x
width = x-5
Step two
the expression for the perimeter of a rectangle is
P=2L+2W
substituting our data
22= 2(x)+2(x-5)
open brackets
22=2x+2x-10
collect terms and solve for x
22+10=4x
32=4x
divide both sides by 4
x= 32/4
x= 8ft
the length is 8ft
the width = x-5= 8-5= 3ft
