The base of a right triangle is 18 cm, and the height is 5 cm. What is the area of the triangle?

Doss [256]

Answer:

45 cm^2

Step-by-step explanation:

The area of a triangle can be found using:

a= (b*h)/2

We know the base is 18 cm and the height is 5 cm. Therefore, we can substitute 18 in for b, and 5 in for h.

a=(18*5)/2

Multiply 18 and 5 first

a=90/2

Divide 90 by 2

a=45

So, the area is 45 cm^2

Find the exact length of the third side. 51

Nesterboy [21]

Answer:

Step-by-step explanation:

You can use the Pythagorean Theorem to solve this:

$a^{2} + b^{2} = c^{2}$

The legs of the triangle are put into either a or b and the hypotenuse is put into c. In this case, they've already given you the hypotenuse, but now you need to find the leg:

$45^{2} + b^{2} = 51^{2}$

2025 + $b^{2}$ = 2601

Subtract 2025 from both sides:

2025 + $b^{2}$ = 2601

-2025 -2025

_____________

$b^{2}$ = 576

Square root:

$\sqrt{b^{2} } = \sqrt{576}$

b = 24
