Answer:

DE = 62°

Step-by-step explanation:

An angle that lies outside a circle and whose sides are 2 secants of the circle is calculated using

∠DAE = $\frac{1}{2}$ (arcDE - arcBC ), that is

12 = 0.5 (DE - 38) ( multiply both sides by 2 )

24 = DE - 38 ( add 38 to both sides ), hence

DE = 62°

Can anyone help me solve question B and explain please please please please please please

Answer:

$m>2$

()***********************

<--------------------(-2)-------(0)------(2)--------------------------->

Step-by-step explanation:

$3m>m+4$

Subtract $m$ on both sides:

$3m-m>m+4-m$

Simplify both sides:

$2m>4$

Divide both sides by 2:

$m>2$

So this means we want values of $m$ greater than 2, not including 2.
