The length of one of the legs of an isosceles right triangle and has a hypotenuse length of seven times the square root of two is 7 units.
<h3>What is an Isosceles triangle?</h3>
Isosceles triangles are triangles that has two of it sides equal to each other. The base angles of an isosceles triangle are equal.
The isosceles triangle is also a right angle triangle. The hypotenuse is the longest side of a right angle triangle.
Therefore,
hypotenuse = 7(√2)
let the length of the other legs = x
Therefore, using Pythagoras theorem
c² = a² + b²
(7(√2))² = x² + x²
49 × 2 = 2x²
98 = 2x²
x² = 98 / 2
x = √49
x = 7 units

Answer:
It will take <u>3 hours</u> for 5 examiners to mark 80 papers.
Step-by-step explanation:
Given:
Time taken by an examiner to mark 80 exam papers = 15 hours
To find time taken by 5 examiners to mark 80 exam papers.
Solution:
Applying unitary method.
One examiner takes 15 hours to mark 80 exam papers
So, in one hour he can mark = papers
In hour 5 examiners can mark = papers
So, we know 5 examiners can mark papers in 1 hours.
So, to mark 1 paper they will take = = of a paper
Thus, to mark 80 papers they will take = hours.
Thus, it will take 3 hours for 5 examiners to mark 80 papers.

Answer:
i cant see the pic could u take another one?
Step-by-step explanation:
First subtract the x variable on both sides so on the first equation youll have -6y=8x+60 then divide 6 on all variables which means youll have y=8/6x+10 and in the second equation you do the same thing and youll have y=-5/6x-11.5
