All the angles should add up to 360°.
8x+10x+9+21x-12+90=360°
Group like terms together.
So,8x+10x+21x+9+90-12=360
39x+87=360
39x=360-87
39x=273
x=7
I believe the correct answer would be $67.22 as the sum of all three
Answer:
<u>Frequency = 1/period = </u>
Step-by-step explanation:
The frequency of the sinusoidal function = 1/period
Frequency is how many the function repeats itself per unit if time i.e: per "1"
For the given graph :
, Where: B = 2π/period
period = 2π/B , B = 1/4 = 0.25
∴ Period = 2π/0.25 = 8π
∴ Frequency = 1/period =
List out all factors of each number, and find the first common one.<span>44</span> : <span>1,2,4</span>
16 : <span>1,2,4,8,16</span>
Therefore, the GCF is <span>44</span>.
List all prime factors of each denominator, and find the intersection of these primes.<span>44</span> : <span>2,2</span>
<span>1616</span> : <span>2,2,2,2</span>
Therefore, the GCF is <span>2×2=4
</span>Divide the numerator (4) by the GCF
<span>4÷4=1
</span>Divide the denominator (16) by the GCF
<span>16÷4=4
</span> Rewrite the fraction in the simplified form
<span><span>14 , and the decimal form will be 0.4.</span></span>
