Answer:
38 crayons
Step-by-step explanation:
It would be 10 more blue crayons than 4 pink crayons so that would be 14 then there would be 6 more green crayons than the blue crayons so 14+6 that equals 20 so its 20+4 so 24 crayons and the 4 crayons came from the pink crayons and then you add 14 too 24 and get 38 crayons hope this helped c:
The value of the sine of the angle J is equal to 5 / 13 (approx. 0.38).
<h3>What is the measure of the missing angle?</h3>
The image attached aside shows us a <em>right</em> triangle with two known <em>side</em> lengths (JL, KJ) and a <em>angle</em> measure (m ∠ K). The measure of the <em>missing</em> angle can be found by using the <em>trigonometric</em> function of cosine:
cos m ∠ J = KJ / JL
cos m ∠ J = 12 / 13
m ∠ J = 22.620°
The measure of the angle J within the triangle JKL is approximately 22.620°.
And the sine of the angle J, which helds the same <em>positive</em> sign than cosine as the angle is in the first quadrant on <em>Cartesian</em> plane, is:
sin m ∠J = √(1 - cos² m ∠J)
sin m ∠J = √[1 - (12 / 13)²]
sin m ∠J = 5 / 13
The value of the sine of the angle J is equal to 5 / 13 (approx. 0.38).

Step-by-step explanation:
x = a + 7
y = b-a
To prove
x + y = b + 7.
- x+y= (a+7) + (b-a)
=a+7+b-a
=a-a+7+b
=0 + 7+b
= b+7
