Answer:
<h3>3/4</h3>
Step-by-step explanation:
![tan = \frac{sin}{cos }](https://tex.z-dn.net/?f=tan%20%3D%20%20%20%5Cfrac%7Bsin%7D%7Bcos%20%7D%20)
<h3> =3/5/4/5</h3>
=3/5 × 5/4
=15/20

=3/4</h3>
Answer/explanation
A is located at point (3, -1) all you need to do is look at the questions divide x from y and see which ones equal the same
Have a great day :)
I believe it's 6/10 total. All I did was add the numerator and denominator.
Answer:
We start at:
|X+6|- 12 < 13
Here we can add 12 to both sides:
|X+6| <13 + 12 = 25
|X+6| < 25
We can separate it in two equations:
if x > -6, then |X+6| = x + 6
(x + 6) < 25
x < 25 - 6
x < 19
if x < -6, then |X+6| = -(x + 6)
-(x + 6) < 25
-x < 31
x > -31
And with those two equations we get:
-31 < x < 19
Required Basic Knowledge.
Rhombus is a parallelogram with equal sides.
i.e.
diagonals bisect eachother. (DE=EB),(AE=EC) &(AED = DEC = CEB = BEA =90°)
And
AD=DC=CB=BA
SOLUTION
——————
Cosider ∆ADE;
AED =90° (refer above details)
given. DAE=30°
DE=6cm (DE=EB; also refer above)
To find:length of AD
Taking Cosine of Angle A
Cos(A) =DE/AD
->Cos(30°) =6cm/(AD)
->(√3/2) = 6cm/(AD)
-> AD =6÷(√3/2) cm
->AD =6×(2/√3) cm
->AD =12/√3 cm (;√3=1.73 .approximately)
->DA=12/1.73 cm
-> DA = 6.936 cm (approx.)
Hope it helps...
