x/2 + 5 = 10
<em><u>Subtract 5 from both sides.</u></em>
x/2 = 5
<em><u>Multiply both sides by 2.</u></em>
x = 10 (This is your answer.)
Using trial and error
x^4+5x^2-36 factors to (x-2)(x+2)(x^2+9)
2x^2+9x-5 factors to (x+5)(2x-1)
so
(x-2)(x+2)(x^2+9)(x+5)(2x-1)=0
set each to zero
x-2=0
x=2
x+2=0
x=-2
x^2+9=0
x^2=-9
x=3√-1
x=3i
x+5=0
x=-5
2x-1=0
2x=1
x=1/2=0.5
roots are
x=-5-2,0.5,2, and the imaginary root 3i
Answer:
Step-by-step explanation:
angle CDA = angle ABC (opposite angles of a parallelogram are equal)
56 degree = angle ABC
therefore angle ABC is 56 degree.
