What is the length of the unknown leg in the right triangle?

Mathematics

Answer:

3

Step-by-step explanation:

The Pythagorean Theorem can be used to determine an unknown side of a right triangle when two sides are known.

It states that a^2+b^2=c^2.

This is where a and b are the legs of the triangle, and c is the hypotenuse.

If you're unclear on this, you can draw a diagram to help you visualize it.

Hence, we can plug the given information into this formula.

a^2+8^2=(√73)^2

Simplify.

a^2+64=73

Subtract 64 from both sides.

a^2+64-64=73-64

a^2=9

Find the square root of both sides.

a=3

The length of the unknown leg in the right triangle is 3 units.

Help me please for the brainliest answer
AveGali [126]

Answer with Step-by-step explanation:

a) {n}^{2}  + 3 \\  \\ n = 1 \\  {1}^{2}  + 3 \\ 1 + 3 \\  = 4 \\  \\ n = 2 \\  {2}^{2}  + 3 \\ 4 + 3 \\  = 7 \\  \\ n = 3 \\  {3}^{2}  + 3 \\ 9 + 3 \\  = 12 \\  \\ n = 4 \\  {4}^{2}  + 3 \\ 16 + 3 \\  = 19 \\  \\ n = 10 \\  {10}^{2}  + 3 \\ 100 + 3  \\  = 103

In this sequence,

1st term = 4

2nd term = 7

3rd term = 12

4th term = 19

10th term = 103

b)2 {n}^{2}  \\  \\ n = 1 \\ 2 \times  {1}^{2}  \\ 2 \times 1 \\  = 2 \\  \\ n = 2 \\ 2 \times  {2}^{2}  \\ 2 \times 4 \\  = 8 \\  \\ n = 3 \\ 2 \times  {3}^{2}  \\ 2 \times 9 \\  = 18 \\  \\ n = 4 \\ 2 \times  {4}^{2}  \\ 2 \times 16 \\ =   32 \\  \\ n = 10 \\ 2 \times  {10}^{2}  \\ 2 \times 100 \\  = 200

in this sequence,

1st term = 2

2nd term =8

3rd term = 18

4th term =32

10th term = 200

Somebody help me 7u7
zvonat [6]

Answer:

105 square feet

Step-by-step explanation:

First of all, find the area of the rectangle (length x width). 7*12 = 84. Now, find the area of the triangle [(base x height)/2]. 6*7 = 42. 42/2 = 21.

Add both of these areas together: 84 + 21 = 105. The area is 105 square feet.
