Answer:
Step-by-step explanation:
-2 * -30 = 60 ( since the multiplication of negatives gives positive )
The length of missing sides x = 5 units and y = 5 units.
<h3>What is Trigonometric ratios?</h3><h3>The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).</h3>
In ΔABC,
AB (Base) = y , BC(Hypotenuse) = , CA (perpendicular) = x
and ∠ABC =
Now,
tan = perp. / base
1 = x /y
x= y .................(i)
again,
sin = perp. / Hypo.
x = 5
put in equation (i), we get
y = 5
Thus, the length of missing side of the given triangle is x = 5 units and y = 5 units.

Answer:
17 animals
Step-by-step explanation:
Rachel has a collection of 40 stuffed animals
3/8 are bears
= 3/8 ×40
= 120/8
= 15
1/5 are dogs
= 1/5×40
= 40/5
= 8
15+8
= 23
Therefore the number of animal she have left can be calculated as follows
= 40-23
= 17
Hence there are 17 animals left
Answer:
Correct answer: C. Ca = 4 Cb
Step-by-step explanation:
Given: Ra = 4 Rb
Ca : Cb = ?
Using the following formula to calculate the circumference of a circle:
C = 2 R π
Cb = 2 Rb π
Ca = 2 Ra π = 2 ·( 4 · Rb) · π = 4 · (2 Rb π) = 4 · Cb
Ca = 4 · Cb
