3x + 2y = 8 5x + 2y = 12

Mathematics
1 answer:
storchak [24]2 years ago
6 0

Step-by-step explanation:

solve simultaneously

subtract the 2 equations like you subtract pure numbers from each other.

5x + 2y = 12

3x + 2y = 8

5x - 3x +2y - 2y = 12 - 8

2x = 4

x = 2

alternatively...

3x + 2y = 8

5x + 2y = 12

-2x = -4

x = 2.

Answer:

TRUE

Step-by-step explanation:

We are given 2 triangles, ∆ABC and ∆DEF.

For the two trinagles to be considered similar, both must have their set of corresponding angles congruent to each other. That is, their corresponding angles are equal.

From the information given, the following are the set of corresponding angles:

<B = <E = 31°

<B = <D = 90°

<C = <F = 59° [180 - (90+31)]

The corresponding angles of both triangles are congruent. Therefore, it is guaranteed that ∆ABC is similar to ∆DEF (∆ABC ~ DEF).
