Is 2.4, 4.5 and 5.2 a right triangle?

grandymaker [24]

Answer:

Step-by-step explanation:

Use the pythagorian theorm to find whether it's a right triangle or not.

So the hyp will be the largest number. And the hyp must be equal to the sum of b and c squared

5.2 squared= 2.4 squared+ 4m5 squared

27.04= 26.01

It's not equal so the triangle isn't a right triangle.

Nastasia [14]

Answer:

$\displaystyle 53.6ft$

Step-by-step explanation:

refer the attachment

let the height be h

since we are given the adjacent side and want to figure out opposite side we'll use tan function

so our equation is

$\displaystyle \tan( {15}^{ \circ} ) = \frac{h}{200}$

cross multiplication:

$\displaystyle h = 200\tan( {15}^{ \circ} )$

by using calculator we acquire:

$\displaystyle h \approx 53.6ft$

hence,

about 53.6ft high in the tree ate monkeys
