Answer:
Length of the hypotenuse = 8.5 units
Step-by-step explanation:
Given the length of the sides of an isosceles right triangle to be 6units
Hint: an hypotenuse is the longest line
To solve this, we use Pythagoras rule
Hypotenuse^2 = adjacent ^2 + opposite ^2
Adjacent = opposite = 6
Let our hypotenuse to be a
a^2 = 6^2 + 6^2
a^2 = 36 +36
a^2 = 72
To get a, let's find the square root of 72
a = 8.485 unit
Therefore, the length of the hypotenuse = 8.5 units
Answer: common difference is 14
Step-by-step explanation:
a,a+d,a+4d
7,7+d,7+4d
(7+d)/7=(7+4d)/(7+d)
(7+d)(7+d)=7(7+4d)
49+14d+d^2=49+28d
d^2-14d=0
d(d-14)=0
d=0 or d-14=0
d=14
