60 because 10×6 hdvehdjdbe... hope it helped
The sum of a series is calculated with the following formula:
n/2(2a+(n-1)d) where n is the number of terms, a is the first term and d is the difference between the terms.
so for this series:
n/2(2*64+(n-1)*-2)=0
n(130-2n)=0
n=0 (not valid because n<1) n=65
so the 65th term gives the sum 0

X= one angle
90-x= complementary angle ( complementary angles adds up to 90 degrees)
x=90-x+42.6
x=-x+132.6(combine like terms)
x+x=-x+132.6+x(add x on both sides)
x=66.3(divide each side by 2)
90-66.3=2
one angle is 42.6 complentary angle is 88 degrees
Answer:124
Step-by-step explanation:
2x + 8 + x - 2 = 180
Add like terms
3x + 6 = 180
Subtract the 6 from both sides
3x + 6 - 6 = 180 - 6
3x = 174
Divide by 3
x = 58
Now we have to find the measure of angle ACD
2(58) + 8 = 124
