I am unsure if this is correct, but I used the Pythagorean theorem to solve your questions.

Step-by-step explanation:

1)

a^2 + b^2 = c^2

13^2 + b^2 = 24^2

b^2 = 24^2 - 13^2

b^2 = 576 - 169 = 407

b = √407 = 20.2

2)

6^2 + 8^2 = c^2

36 + 64 = c^2

100 = c^2

c = 10

10 + 6 + 8 = 24

Step-by-step explanation:

n+2n+1+5n-6=15

= 8n + 1 - 6= 15

= 8n + 1 - 6 + 6 = 15 + 6

= 8n +1 = 21

= 8n + 1 - 1 = 21 - 1

=8n = 20

= 8n / 8 = 20 / 8

= n = 2.5

the value of ‘n’ is 2.5
