Answer:

39) Opt. A (24)

Step-by-step explanation:

39) 40 - 8(n) where n = 2

=> 40 - 8*2

=> 40 - 16

=> 24 Opt. A

And just for information, the answer you marked for 38th is wrong.

Formula = bh/2

b = 16

h = 12

bh/2 = 16*12/2

        =192/2 = 96

Hope this helps u

Please mark as brainliest

Thank You

The lines a and b intersect at point C.<br><br> What is the value of y?
Amanda [17]

Using the definition of vertical angles, the value of z is: 15.

<h3>Vertical Angles Pair</h3>

The two pairs of opposite angles formed when two straight lines intersect are called vertical angles, and are therefore congruent to each other.

Thus:

2z + 10 = 40

2z = 40 - 10

2z = 30

z = 30/2

z = 15

Therefore, using the definition of vertical angles, the value of z is: 15.
