in a figure AD = 13 cm BC = 12 CM ab = 3 cm and angle ACD = angle abc = 90 degree find the length of DC​

i think it would be 42cm

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
