Answer:
Step-by-step explanation:
Since two sides of the triangle are equal in length, we can conclude that is an isosceles triangle. With this information, we can draw an isosceles triangle to find
. Since the base angles of an isosceles triangle are equal, we can solve for
:
(Angle sum of triangle is
)
(Base angles of isosceles triangles are equal, there is an image attached to show that
is one of the base angles)
Hope this helps :)
Answer:
The cost of the system is $163 and The cost of the games is $489
Step-by-step explanation:
∵ A video game system and several games are sold for $652
∵ The cost of the games is 3 times as much as the cost of the system
→ Assume that the cost of the system is $x
∵ The cost of the system = x
∴ The cost of the games = 3 × x = 3x
∵ The total cost of the system and the games = 652
→ Equate the sum of the cost of the system and the cost of the games
by 652
∴ x + 3x = 652
→ Add the like terms in the left side
∴ 4x = 652
→ Divide both sides by 4 to find x
∵
∴ x = 163
∵ The cost of the system = x
∴ The cost of the system is $163
∵ The cost of the games = 3x
∴ The cost of the games = 3(163) = 489
∴ The cost of the games is $489
