Answer:
The correct answer is option D. 5.7 units
Step-by-step explanation:
It is given a square, Its diagonals meet to form four right angles
<u>To find the value of x</u>
From the figure we can see that the triangle with sides x, x, 8 have angles 45°,45° and 90°
If the angles are 45°,45° and 90° then sides are in the ratio 1 : 1 : √2
Here x : x : 8 = 1 : 1 : √2
Therefore x = 8√2 = 8/1.414 = 5.6577 ≈ 5.7 units
Therefore the correct answer is option D 5.7 units

Discounted price X
————————— = ———
Original Price 100
45 x
—- = —-
72 100
Cross multiply
45 times 100= 4500
72 times x= 72x
72x=4500
Divide
4500/72= 62.5%
Answer:
(30-5n)
Step-by-step explanation:
The given sequence is :
25,20,15,10,5
Here,
First term, a = 25
Common difference = 20-25 = -5
We need to find the nth term of the given sequence. The formula for the nth term is given by :

So, the nth term of the above sequence is (30-5n).
Answer:
ZWU ~ WYU
WY = 2.5
UY= 1.5
Step-by-step explanation:
ZUW ~ WUY ~ ZWY
5/3=x+1/x
Cross multiply
5x=3x+3
2x=3
x=3/2 OR 1.5
