URGENT!!! WILL MARK BRAINLIEST!<br> Find the measure of Angle DBE then find the measure of ∠ABD?
dedylja [7]

Answer:

m<DBE =50°

m<ABD=150°

Step-by-step explanation:

Because of Straight Angles, All the angles will add up to 180 degrees

Let x be m<DBE

40+x+70+20=180

x+130=180

x=50

m<DBE will be 50 degrees

To find the m<ABD, we add m<FBA, m<FBE, m<DBE.

70+50+30=150

m<ABD = 150

Please help asap, it would be much appreciated!! :) Thank you so much!!
LiRa [457]

Statement 1 is false.

While it is true that some of the y-values have more than one corresponding x-value, this does not make the relation not a function.  It would not be a function if some of the <em>x-values</em> had more than one corresponding y-values.

Statement 2 is true.

The domain of a function is all the x-values it encompasses.  This function starts at 3 and ends at 8.

Statement 3 is false.

The range of a function is all the y-values it encompasses.  This includes all the y-coordinates, but it does not express the range properly.  The range is [6, 10].

Hope this helps!!
