K is the middle letter of the triangle JKL so it would be the same as the middle letter of the triangle EFG
so K = F
F = 62 degrees, so K = 62 degrees
Answer:
x = 0.666666 & x = 2/3 in fraction form
Step-by-step explanation:
4-2/4x=3/4
we're solving for x so we have to get x on its own
multiply 4x bc it's the denominator of the fraction
we're left with -->
4-2=3/4 * 4x
4-2 is 2
2=3/4 *4x
divide by 3/4 to get x alone
2*2/4=2.6666667
2.66667=4x
divided by 4 on both sides is
you'll get 0.66666 = x since you don't want to use fractions
Given that the recursive formula is:
an=an-1+7
first term is
a1=17
the second term will be:
a2=a(2-1)+7
a2=a1+7
a2=17+7
a2=24
To evaluate for the explicit formula we use the formula:
an=a+d(n-1)
where
a=first term
d=common difference
from the calculations above:
d=24-17=7
thus the explicit formula will be:
an=17+7(n-1)
an=17+7n-7
an=7n+17-7
an=7n+10
Answer: B] an=7n+10
