What are the factors of the expression?

Phantasy [73]

<span>2/5 a b To get the number of factors, simply take each item from the expression and isolate it. Given the formatting limitations, I can't write the factor 2 over 5 and will instead represent it as 2/5. So the expression is 2/5ab where there's an implied multiplication between all the factors. Making that multiplication explicit, the equation becomes 2/5 * a * b And each possible factor also becomes quite explicit. Namely, the factors are 2/5 a b The reason that the 2 and 5 aren't considered factors is because technically, you could consider the 2 to be a factor, there isn't a corresponding factor of 1/5. So you have to consider 2/5 to be a single entity.</span>

Answer:

Solution not exists.

Step-by-step explanation:

Since in a certain step a certain amount divided by zero, an that stage the quentity is undefined. That is if,

$\frac{5360070001+624-7646}{7000+1000000000-5000,000,000}-12+122500050,000,000,000,000,000,000=X$

Then, at the next stage, $\frac{X}{0}$ is not exists, wheather after it divided by 1 or not. Thus required solution is not exists.

Pls help! <br> and a reason.

Rasek [7]

Answer:

$\angle BDA = 72^{\circ}$

$\angle DAB = 36^{\circ}$

$\angle BDC = 108^{\circ}$

$\angle BCD = 36^{\circ}$

$\angle DBC = 36^{\circ}$

Step-by-step explanation:

Given

$\angle ABD = 72^{\circ}$

Required

Determine the missing angles

Since AB = AD, then:

$\angle ABD = \angle BDA$ --- Base angles of an isosceles triangle

Hence:

$\angle ABD = \angle BDA = 72^{\circ}$

$\angle ABD + \angle BDA + \angle DAB = 180^{\circ}$ --- angles in a triangle

$72^{\circ} + 72^{\circ} + \angle DAB = 180^{\circ}$

$144^{\circ} + \angle DAB = 180^{\circ}$

Collect Like Terms

$\angle DAB = 180^{\circ} - 144^{\circ}$

$\angle DAB = 36^{\circ}$

$\angle BDA + \angle BDC = 180^{\circ}$ --- angle on a straight line

$72^{\circ} + \angle BDC = 180^{\circ}$

$\angle BDC = 180^{\circ} - 72^{\circ}$

$\angle BDC = 108^{\circ}$

Since ABC is isosceles, then:

$\angle DAB = \angle BCD = 36^{\circ}$ --- base angle of isosceles

$\angle BCD = 36^{\circ}$

Lastly:

$\angle BCD + \angle BDC + \angle DBC = 180^{\circ}$

$36^{\circ} + 108^{\circ} + \angle DBC = 180^{\circ}$

$\angle DBC = 180^{\circ} - 36^{\circ} - 108^{\circ}$

$\angle DBC = 36^{\circ}$
