The legs of a right triangle are 4 units and 7 units. What is the length of the hypotenuse?A. square root 33 units
B. square root 65 units
C. 33 units
D. 65 units

Answers

Answer:

Correct option is:

B. square root 65 units

Step-by-step explanation:

Pythagorean theorem states that the square of hypotenuse is equal to the sum of squares of the legs of the right angled triangle.

Here, we are given that:

The legs of a right triangle are 4 units and 7 units.

By Pythagoras theorem

Hypotenuse²=4² +7²

= 16+49

= 65

⇒ Hypotenuse= $√(65)$

Hence, Correct option is:

B. square root 65 units

the square root of 65 units

Answer:

$a_(n)=12n-8$

Step-by-step explanation:

We have been given a recurrence relation $a_(n+1)=a_(n)+12$ and the first term of the sequence $a_(1)=4$ .

We can rewrite the given recurrence relation as: $a_(n+1)-a_(n)=12$

We know that if difference between two consecutive terms is always constant, the sequence is called an arithmetic sequence. So we are dealing with an arithmetic sequence with first term as 4 and common difference as 12.

We can therefore, write an explicit formula for nth terms of the sequence as.

$a_(n)=a_(1)+(n-1)d\na_(n)=4+(n-1)(12)\na_(n)=4+12n-12\na_(n)=12n-8\n$
