Answer:
ABD= 58
BDC= 32
Step-by-step explanation:
complementary = 2 angles equal 90 degrees.
8y+2=90
Subtract 2 both sides.
8y=88
y=11
That's not all, put y into the equations.
ABD
5(11)+3
Multiply
55+3=58
BDC
3(11)-1
MULTIPLY
33-1
SUBTRACT
32
42.365
i used a calculator
$1.56
125.32 : 80.5 = 1.55677 => ~1.56$
(x - y)(j - s).
jx + sy - sx - jy
= jx - sx + sy - jy
= x(j - s) - y(j - s)
= (x - y)(j - s).
here you go
i hope this helps
