klemol [59]
Hypotenuse ^2 = base^2 + perpendicular ^2

H^2 = 6^2 + 8^2
H^2 = 36 + 64
H^2 = 100
H = 10

(This is a right angle triangle as 60+30= 90

Simplify <br>(8/14 - 2/8) + 1/7​
konstantin123 [22]

Answer:

13/28.

Step-by-step explanation:

(8/14 - 2/8) + 1/7

We can just remove the parentheses and simplify its contents:

=  4/7 - 1/4 + 1/7

= 4/7 + 1/7 - 1/4

= 5/7 - 1/4      The LCD of 7 and 4 is 28 so we have:

20/28 - 7/28

= 13/28.
