Answer:
∠1 = 90°
∠2 = 66°
∠3 = 24°
∠4 = 24°
Step-by-step explanation:
Usually the diagonals of a rhombus bisect each other at right angles.
Thus; ∠1 = 90°
Since they bisect at right angles, then;
∠R1S = 90°
Now, sum of angles in a triangle is 180°
Thus;
66° + 90° + ∠4 = 180°
156 + ∠4 = 180
∠4 = 180 - 156
∠4 = 24°
Now, also in rhombus, diagonals bisect opposite angles.
Thus; ∠4 = ∠3
Thus, ∠3 = 24°
Similarly, the diagonal from R to T bisects both angles into 2 equal parts.
Thus; ∠2 = 66°
Answer: 40 minutes
Step-by-step explanation:
It takes 16 minutes for the first 2 stations to water their sections which means that the time taken per station is:
= 16/2
= 8 minutes per station
Ms. Reynolds has 5 stations.
Total time taken will therefore be:
= 8 * 5
= 40 minutes
Answer:
D) 32,357mm^3
Step-by-step explanation:
Given
First, we calculate the volume of 1 roll.
The volume of the cylinder is:
Where
And the thickness represents the height.
So:
The volume is:
The volume of the 40 is:
The closest option is (d):
Start by y-k=m(x-h)
m= 3
k=2
h=1
so y-2=3(x-1)
distribute
y=3x-3+2
final answer: y=3x-1
Answer:
angle 1=
°
Step-by-step explanation:
to find the angle of 1 you should know angle 2, what is angle 2?
angle 
° and angle 
are symetrical so they have the same value.
now that we know that angle 2 is equal to °
then what is angle 1
if the whole line has an angle of 
° and angle °.
so the equation will be :
flip the equation to find 
:
the angle 1 which we found in the given equation is 135
check if my answer is correct is :
my equation is correct
