Answer:
both
Step-by-step explanation:
angle ABC is an isoceles triangle since BC and AB are equal. If you look at the other two triangles they are also isoceles because they have 2 equal sides as well.
{x-(-3/4)}^2=3^2
(x+3/4)^2=9
{(4x+3)/4}^2=9
(4x+3)^2/16=9
(4x+3)^2=9*16
16x^2+2*4x*3+3^2=144
16x^2+24x+9=144
16x^2+24x+9-144=0
16x^2+24x-135=0
in decimal formation it is -0.5 and in fraction -1/2
9) 4/50 = 0.08 = 8%
10) 65 * 0.20 = 13
