Plz as fast question: which shows a right triangle

D

Step-by-step explanation:

A right triangle has one angle that is exactly 90o. 89o will not do. 91o is too far away. It must be 90 with no rounding.

D is the only triangle that fits that description.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
