A) 21.2 cm
B) 18 cm
C) 26.9 cm
D) 22.9 cm

D) 22.9 cm

Step-by-step explanation:

This is a right triangle so we can use the Pythagorean theorem

a^2 + b^2 = c^2

10^2 + x^2  = 25^2

100 + x^2 = 625

Subtract 100 from each side

x^2 = 525

Take the square root of each side

sqrt(x^2) = sqrt(525)

x =22.91287857

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

step-by-step explanation:

y∈r, 8> y≥0

hope i !

p.s the first bit only matters if you know what that means.

p.p.s brainliest would really
