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°

Answer:

m = 3/2

b = 0

y = 3/2x

Step-by-step explanation:

M is the slope, which is the rise/run of a line.

Using this, we know m is 3/2.

B is the y-intercept, which is where the line crosses the y-axis. In this case, B equals 0.

We use this information to put together our final equation of y= 3/2x (since B equals 0, there is no + or - after the slope)
