Answer:

Attached below is the missing figure

answer : ∠ABD = ∠AbC + ∠ CbD

Step-by-step explanation:

when Line BC is drawn to divide ∠ABD equally

solving each angle :

∠ABD > ∠AbC also angle

∠ABD > ∠ CbD

∴ ∠ABD = ∠AbC + ∠ CbD

assuming ∠B = 60°

therefore ∠b = 60 / 30 = 30°

Answer:

$x =320$

Step-by-step explanation:

Given

$x^2 + 200x = 166400$

Required

Find x

We have:

$x^2 + 200x = 166400$

Rewrite as:

$x^2 + 200x - 166400 = 0$

Expand

$x^2 + 520x - 320x - 166400 = 0$

Factorize

$x(x + 520) - 320(x + 520)= 0$

Factor out x + 520

$(x - 320) (x + 520)= 0$

Split

$x - 320 = 0\ or\ x + 520= 0$

Solve

$x = 320\ or\ x =- 520$

Side length must be positive;

So:

$x = 320$
