Find the values of x and y .
Pani-rosa [81]
X = ?, y = ?;
2 x - 70° = x + 30°
2 x - x = 30° + 70°
x = 100°
x + 30° + 5 y = 180°
130° + 5 y = 180°
5 y = 180° - 130°
5 y = 50°
y = 50° : 5
y = 10°
Answer: C ) x = 100,  y = 10

Help please :) im not too good at math aha
DIA [1.3K]

Answer:

x = 3 and y = 2

Step-by-step explanation:

For the triangles to be congruent.

The hypotenuse and a leg of one triangle and the hypotenuse and a corresponding leg of the other triangle must be congruent, that is

x = y + 1 → (1) congruent legs

3y = x + 3 → (2) congruent hypotenuse

Substitute x = y + 1 into (2)

3y = y + 1 + 3, that is

3y = y + 4 ( subtract y from both sides )

2y = 4 ( divide both sides by 2 )

y = 2

Substitute y = 2 into (1)

x = 2 + 1 = 3
