Answer:
The number of games for Xbox is about 155
The number of games for PS4 is about 175
Step-by-step explanation:
Let us find the numbers of games for Xbox and for PS4 game
∵ There are 330 video games in the store
∵ 47% of them were for Xbox
- Multiply 47% by 330
∴ The number of games for Xbox = 47% × 330
∵ 47% =
∴ The number of games for Xbox = × 330
∴ The number of games for Xbox = 155. 1
∴ The number of games for Xbox ≅ 155
∵ 53% of them were for PS4
- Multiply 53% by 330
∴ The number of games for PS4 = 53% × 330
∵ 53% =
∴ The number of games for PS4 = × 330
∴ The number of games for PS4 = 174.9
∴ The number of games for PS4 ≅ 175
Answer:
Triangle 1: x = 80 degrees, acute
Triangle 2: x = 10 degrees, right
Step-by-step explanation:
Triangle 1:
By the Sum of Interior Angles Theorem, all the angles inside the triangle adds up to 180 degrees. So, set up this equation:
Solve for x:
So, x = 80 degrees
Because all the angles are less than 90 degrees, this is an acute triangle.
Triangle 2:
By the Sum of Interior Angles Theorem, all the angles inside the triangle adds up to 180 degrees. So, set up this equation (with the right angle given):
Solve for x:
So, x = 10 degrees
Because there is an angle measuring 90 degrees, this is a right triangle.
