in the following diagrams ABD=y,DBC=x,EFH=y, EFG=x and PQS=SQR=x.write the following in terms of x and y ABC
Leokris [45]

Angles are the space between intersecting lines, and they are measured in degrees or radians

The measure of angle ABC is y + x

<h3>How to determine angle ABC</h3>

The given parameters are:

ABD=y,

DBC=x,

EFH=y,

EFG=x

PQS = SQR = x

To determine the measure of angle ABC, we make use of angle ABD and angle DBC

Note that angle ABD and angle DBC have common vertices at points B and D

So, we have:

ABC = ABD + DBC

Substitute known values

ABC = y + x

Hence, the measure of angle ABC is y + x

Someone quickly hell
Elza [17]

Answer:

£3,780

Step-by-step explanation:

Total rows = 19 rows

Seats per row = 28 seats

Cost of tickets per seats = £8.75

Total number of seats at the concert = Total rows × seats per row

= 19 rows × 28 seats

= 532 seats

The tickets for 100 seats have not been sold

Total number of tickets = sold tickets + unsold tickets

532 = sold tickets + 100

532 - 100 = sold tickets

432 = sold tickets

Sold tickets = 432 tickets

Total cost estimate of sold tickets = sold tickets × cost of tickets per seats

= 432 × £8.75

= £3,780
