In figure AB and CD bisect each other at O. State the 3 pairs of equal parts in ∆AOC and ∆BOD. Is ∆AOC ≅ ∆BOD? Give reasons

GuDViN [60]

Answer:

SEE EXPLANATION

Step-by-step explanation:

$In\:\triangle AOC \:\&\:\triangle BOD$

$AO \cong OB.... (given)$

$\angle AOC \cong\angle BOD$

$(vertical \: \angle s)$

$CO \cong OD.... (given)$

$\therefore \triangle AOC \:\cong\:\triangle BOD$

$(SAS \: postulate)$

So, the 3 pairs of equal parts in ∆AOC and ∆BOD are:

$AC = BD$

$m\angle OAC = m\angle OBD$

$m\angle OCA = m\angle ODB$

X+2y=10 6y=--3x+30 Use algebraic rules of equations to predict the solution to the system of equations.

MaRussiya [10]

X + 2y = 10 . . . (1)
6y = -3x + 30 . . . (2)

From (2), 3x + 6y = 30
3(x + 2y = 10)
3 x (1)

Since, the second equation is a multiple of the first equation, the system will have an infinitely number of solutions.

Solve for W <br> 4w^2+9w= -2

7nadin3 [17]

Answer:

$w_1=-\frac{1}{4},w_2=-2}$

Step-by-step explanation:

$4w^2+9w=-2$

$4w^2+9w+2=0$

$w^2+9w+8=0$

$(w+1)(w+8)=0$

$(4w+1)(w+2)=0$

$w_1=-\frac{1}{4},w_2=-2}$
