The number is 3 times the sum of its digits
45 is added = 4+5=9 so,a common numbers in 3rd and 9th table
9,18,27,36,45...
27+45=72
2+7=9
or
<span>4+5=9</span>
Which of the following accurately describes cot(336°)
Options are
cot(-336°)
cot(24°)
cot(-24°)
-cot(-24°)
Answer : cot(-24°)
In a circle the total angle is 360 degrees. 336 degree lies in fourth quadrant.
360 degree - 336 degree = 24 degree
+24° lies on first quadrant and -24° lies on fourth quadrant.
So cot(336) is same as cot(-24)
Answer:
w = 3
l = 10
Step-by-step explanation:
l = 4w-2
P = 26cm
P = (l + w) × 2
26 = (4w-2+w) ×2
26 = (4w + w - 2) × 2
26 = ( 5w - 2 ) × 2
26 ÷ 2 = 5w -2
13 = 5w - 2
13 + 2 = 5w
15 = 5w
w = 3
l = 4w - 2
l = (4 × 3) -2
l = 12 - 2
l = 10
Answer:
Step-by-step explanation:
As for the angles of both triangles; they’re the same. The sides are 1:2.
I’m giving you formulas that are labeled: side a shortest
” b mid length
” c hypotenuse
angle α(alpha) opposite side a
” β(beta) ” ” b
” γ(gamma) ” ” c
A major formula for rt triangles is: a^2+b^2=c^2.
*Another is: a/sinα=b/sinβ=c/sinγ.
Remember α+β+γ=180°.
As for sides a&b use the above formula.
As for <ACB; the angle is γ which is a rt <.
Given: tan<x=5/2+1/2=6/2=3atan=71.565……….°=β. So α=18.44…….°. γ= rt angle.
To get the sides use the formulas at *.
