When a quadrilateral is inscribed in a circle, the opposite angles are supplementary.
x + 6x + 19 = 180
7x + 19 = 180
7x = 161
x = 23

Now solve for B.
6(23) + 19 = B
138 + 19 = B
157 = B

The measure of angle B is 157 degrees

Hope this helps =)

Find the values of x and y. Show your work.

Ira Lisetskai [31]

7x-4=31
7x=31+4
7x=35
x=35/7=5

4y+8=24
4y=24-8
4y=16
y=16/4=4

Hence, x=5;y=4

yan [13]

Answer:

The expression is 42-17-19 OR 42-(17+19).

Step-by-step explanation:

First, we can indicate that we can use subtraction because is giving them away for his birthday.

"He gave one each to the 17 students in his class and to the 19 students in the other third-grade class".

That represents taking away 17 and 19 means that it is subtracting them.

Hope this helps. (:

Two cars at the same point on I-75. One heads north going 75mph and one heads south going 60mph. How long will it take for the c

Mice21 [21]

It will take 3 hours 6 minutes 40 seconds for the cars to be 420 miles apart.

Step-by-step explanation:

Step 1; The cars are traveling in the opposite direction at different speeds. One is going north at a speed of 75 mph while the other is going 60 mph. So for every hour, the cars are traveling they increase the distance between in between themselves by 75 miles + 60 miles = 135 miles.

Step 2; Assume that in x hours the distance between them is 420 miles. To calculate x we divide the distance to be traveled by the distance being traveled every hour.

x = distance to be covered / distance being traveled every hour

= 420 / 135 = 3.11 hours

We multiply the 0.11 hours with 60 to convert it into minutes. 0.11 × 60 = 6.66 minutes and if we do the same for seconds, 0.66 minutes × 60 = 40 seconds.
