We know that
In <span>a right triangle
c</span>²=a²+b²
where
a and b are the legs of triangle
c is the hypotenuse of the triangle
so
case 1)7,24,25
25²=7²+24²
25²-----> 625
7²+24²----> 625
625 is equal to 625----------> <span>form a right triangle
</span>
case 2) 7,23,24
24²=7²+23²
24²------> 576
7²+23²-----> 578
576 is not 578-------------> not form a right triangle
case 3) 7,25,26
26²=7²+25²
26²-----> 676
7²+25²-----> 674
676 is not 674-----> not form a right triangle
the answer is
7,24,25 form a right triangle
Answer:
78
Step-by-step explanation:
for the right side we can just do 14*2 since there are two people per seat and 14 rows
14 *2 is 28
for the left side we just do 14*3 since there are three people per seat and 14 rows
14*3 is 42
Then we have to add the 8 students that can fit in the very back seat
42 + 28 + 8
28 + 8 is 36
42 + 36 = 78
Answer:
T3 = 30
Step-by-step explanation:
9x + 3y - 6z = 18. 6. 3x-5y+10z= 15.
10x + 4y+5z = 20
