My question.
please Help

Step-by-step explanation:

1. Here we are going to add x plus 54 equalling to 90° as done below

x + 54° = 90°

x+ 54° + 54° = 90° - 54°

x + 0° = 36°

x = 36°

after that we are going to get the value of y

y + 39° = 180°

y + 39°-39° = 180° -39°

y + 0° = 141°

y = 141°

just as we did when getting the value of x

2.here in number 2 we are going to just add

m + 140° + 28° = 360°

m +168° =360°

m +168°-168° = 360°-168°

m +0° = 192°

m = 192°

3. here in Number 3 see below

values of a,b,c and d

value of a

a +50° = 180°

a +50°-50° = 180°-50°

a +0° = 130°

a= 130°

value of b

b = 60° there is no explanation am sorry

value of c

c = 30° no explanation sorry

then the value of d

d + 38° = 90°

d +38°-38°= 90°-38°

d+0° = 52°

d = 52°

hope that will help you

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
