360° - 90° - 26° = 244°
244° ÷ 2 = 122°
Answer:
the duplicate ratio of a : b
= a²/b²
Step-by-step explanation:
for example:-
for understanding
if u wanna find the duplicate ratio of 4:5
so,
4²/5²= 16/25
•°• 16:25
16:25 is your duplicate ratio of 4:5
Answer:
Step-by-step explanation:
1st= 11/16
AC= 7.5
CD= 2.0625
this will equal 86 is the anwer to question u have asked
Answer:
x=-1
Step-by-step explanation:
x3+x2=-9x-9
add 9x +9 on each side
x^3+x^2+9x+9=-9x-9+9x+9
x^3+x^2+9x+9=0
factor out an x^2 from the left 2 terms and a 9 from the right 2 terms
x^2 (x+1) +9(x+1) = 0
factor out x+1
(x+1) (x^2+9) = 0
using the zero product property
x+1 =0 x^+9 =0
x=-1 x^2 =-9
x=-1 sqrt(x^2) = sqrt(-9)
x=-1 x = ±3i
