Answer:

1.  Find < ACB

2. Use that triangles =180 to find <B  = 41

Step-by-step explanation:

1.We need to find < ACB

<ACB +<DBC= 180 They make a straight line

Subtract DBC from each side

<ACB = 180 - <DBC  

We know DCB = 113

ACB = 180 -113

ACB = 67

2.The three angles of a triangle = 180, so we can then find <B

<A +<B + <ACB = 180

72 + B + 67 = 180

Combine like terms

139+ <B = 180

Subtract 139 from each side

<B = 180-139

<B =41

Okay so this is all about interior angles.

And interior angles all add up to 180.

Since 113 is an exterior, you need to find the interior of C.

180-113=67°

Interior of C is 67°

Add 67 and 72.

now, 180=B+139

Subtract 139 from 180.

Your answer should be AngleB= 41°

Two airplanes leave an airport at the same time and travel in opposite directions. One plane travels 95 km per hour faster than
andrew-mc [135]

Answer:

887 and 792 km per hour

Step-by-step explanation:

Lets call the first plane A and the second B

we know that: a=b+95

We can say that 3358=2b+(2b+190)<=A

When solved, we get 3168=4b

b=792 km per hour.

Go back to step two. A=b+95, so A=792+95=887 km per hour

The two planes rates are 887 km per hour and 792 km per hour.

One number is 3 less than a number. If 4 times the smaller number minus 3 times the larger number is 4, find the two numbers
Shalnov [3]

x = y - 3

4x - 3y = 4

4 (y - 3) - 3y = 4

4y - 12 - 3y = 4

y = 16


x = 16 - 3

x = 13
