Ok so angle ABC we’re gonna call it X

Angle BCD is 2X

The trick is the sum of angles of a pentagon is 540 degrees.

90 + 115 + 125 + 2X + X = 540
3X = 540-330
X = 70

SoOoOoOoOooooo

Angle BCD is 140 degrees !!

irga5000 [103]

We have been given that Jin cut a round gelatin dessert into 8 equal pieces. Seven of the pieces were eaten. We are asked to find the angle measure of the dessert that was left.

We know that there are 360 degrees degrees in a circle all the way around the center.

Since Jin cut all pieces of same size, so angle measure of all pieces will be equal.

To find the angle measure of each piece, we will divide 360 by 8.

\text{Angle measure of each piece of dessert}=\frac{360^{\circ}}{8}

\text{Angle measure of each piece of dessert}=45^{\circ}

Therefore, the angle measure of the dessert left dessert piece is 45 degrees and option D is the correct choice.

patriot [66]

Answer:

48,58

Step-by-step explanation:

Let The speed of the west bound train be x

Let the east bound train be x+10

The speeds can be calculated as follows

2(2x+10)= 232

4x + 40= 232

4x= 232-40

4x= 192

x= 192/4

= 48

Hence the speedof the west bound train is 48

The speed of the east bound train is 48+10

= 58
