2 answers:

7 0

30x + 20 = 50

20 + -20 + 30x = 50 + -20

0 + 30x = 50 + -20 30x = 50 + -20
50 + -20 = 30 30x = 30

x = 1

30x - 20 = 50
use inverse operations to isolate x

30x - 20 = 50
+ 20 +20

30x = 70
(30x = 70) /30

x= 7/3 (this is the simplified term)

Leto [7]

Answer:

x = 8 in

y = 8sqrt(2) in

Step-by-step explanation:

x = 8

AC = BC

Because opposite angles are equal.

8² + 8² = hyp²

hyp² = 64 + 64 = 128

hyp = sqrt(128)

hyp = 8sqrt(2)

Where sqrt is the square root
