Find the values of each variable

x = 38°

y = 104°

Step-by-step explanation:

You have to find the value of x and y.

All angles on a straight line are equal to 180° also called supplementary angles.

Step 1: Find y

76 + y = 180° (because supplementary angles)

y = 180 - 76

y = 104°

Step 2: Find x

2x + y = 180° (because supplementary angles)

y = 104°

2x + 104 = 180°

2x = 180 - 104

2x = 76

x = 76/2

x = 38°

Therefore, y = 104° and x = 38°.

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.

answer: this doesnt make any sense especially the photo.
