Answer:
x = 6.5
Step-by-step explanation:
Since all angles in a triangle adds up to 180°, we have:
10x - 10 + 10x + 8 + 8x = 180
28x - 2 = 180
28x = 182
x = 182/28 or 6.5
Subtract the difference in age from the total:
87 - 15 = 72
Divide by 2:
72 / 2 = 36
Sydney is 36 years old
Devaughn is 15 years older: 36 +15 = 51 years old
51 + 36 = 87
Answer:
1/(k^2)
Step-by-step explanation:
Because the k's are above one another in the fraction format, using exponent rules you would subtract the top number exponents with the bottom number exponents (note do not do anything with the letter k). 5-7= -2, and k^-2 is the same as 1/(k^2).
Hope you have a great day and this helps! :)
