The triangle has two angles of 45°, so the straight legs a are equal. Pythagoras says that

a² + a² = 16², so 2a² = 256, a = √128 = √64·√2 = 8√2

2x – 3y = -5

vampirchik [111]

Answer:

y = 3

Step-by-step explanation:

2x-3y = -5 --------- (1)

y = 2+x ------- (2)

substitute (2) into (1)

2x-3y = -5

2x-3( 2+x ) = -5

2x-6-x = -5

2x-x = -5+6

x = 1

substitute x = 1 into (2)

y = 2+x

y = 2+1

y = 3
