Answer:

x=40

Step-by-step explanation:

if you add the angle with a value of (x) to the angle with a value of (4x - 20) the sum will be equal to 180 degrees because a straight line is created with the sum of the two angles. A straight line is basically just an angle with a value of 180 degrees.

x+(4x-20)=180

5x-20=180

5x=200

x=40

Angle B=180-(38+31.6)=110.4
by law of sin
sin B/b=sinA/A
sin(110.4)/b=sin38/25
b=25*sin(110.4)/sin(38)=38.06

1) Miguel has a gift card to an electronics store. He has $ 150 on the card. He purchased a DVD for $ 20 and some games for $12.

GrogVix [38]

Answer:

9 games

Step-by-step explanation:

If he purchase 1 game, he spent $12.50. If he purchased 2 games, he spent 2(12.50) = $25.

This means he spent 12.5x for x number of games.

His total spending will be 12.5x + 20. He has $17.50 left on the card from $150.

150 - (12.5x + 20) = 17.5

150 - 12.5x -20 = 17.5

130 - 12.5x = 17.5

-12.5x = 17.5 - 130

-12.5x = -112.5

x = 9
