The triangles in the diagram are congruent. If mF = 40°, mA = 80°, and mG = 60°, what is mB?
maria [59]

Answer:

The answer is 40 degrees.

Step-by-step explanation:

Since the two triangles are congruent, which means they are the same shape and size, they share the same angle measures. Since angle B is the same as angle F, it equals 40 degrees.


I hope this helped! :-)

A new computer has a model number, a part number, and a serial number. The model number is assigned by the manufacturer to ident
kumpel [21]
<span>(serial number, model number)

That's a function mapping each serial number to its model number.

 (part number, serial number)

That's not a function; the same part number is in computers with different serial numbers

</span><span> (model number, part number)
</span><span>
That one's a bit confusing.  Normally a given model would have more than one part number inside so this isn't a function.  But here the description says there's only one part number for each model, so that would be a function.

(model number, serial number)

Not a function, more than one serial number for a given model number.

The area of a trapezoid is 864 cm2. It has a height of 24 cm, and the length
Paha777 [63]

Answer:

Step-by-step explanation:

Area of trapezium = 1/2 × h (a+b) = 864 cm^2

where h is the height and a and b are the two parallel sides

h = 24 cm

a = 30 cm

b = ?

1/2 × 24 ( 30 + b ) = 864

12 ( 30 + b ) = 864

30 + b = 864/12

30 + b = 72

b = 72 - 30

b = 42

Therefore the lenght of other base = 42 cm

Plz mark it as brainliest !!!!!!!!!!
