Given:
The figure of a right angle triangle with hypotenuse 10 and two angles 
To find:
The lengths of the legs.
Solution:
Two angles are given. By using the angle sum property, the third angle is:
Third angle = 
= 
Base angles are equal it means the given triangle is an isosceles right triangle. So, the lengths of both legs are equal.
Let x be the lengths of both legs. Then by using Pythagoras theorem, we get
Taking square root on both sides, we get
The side length cannot be negative. So, the only value of x is 
.
Therefore, the length of the both legs is units.
Answer:
$9600
Step-by-step explanation:
Given data
Charge per hour= Rs.1200 per hour
Number of hours = 8 hours
Hence the cost of the rental for 8 hours is
=1200*8
=$9600
Answer:
(-∞, -4] or [5, ∞)
Step-by-step explanation:
Because the solutions for x can also be equal to -4 and 5, brackets are used.
And because the solutions for x can be any number less than -4 or any number greater than 5, -∞ and ∞ are used respectively.
For this question you should first find a pack of one toilet roll for each cost so you can say :
if 9 toilet rolls cost 4.23 so 1 toilet roll is : 4.23/9 = 0.47
and if 4 toilet rolls cost 1.96 so 1 toilet roll is : 1.96 /4 = 0.49
so 0.49 is greater than 0.47 so a pack of 9 toilet rolls gives the better value for money :)))
i hope this is helpful
have a nice day
Answer:
( n-2) 180°
Step-by-step explanation:
a polygon is a flat shape it has same angles and same sides to find the interior we take the formular and divide it by the number of its sides. ( n-2) 180° ÷n
