Answer:
The sum of all the angles of an isoceles triangle is 180°
So it's 50° + 2x° = 180°
50 + 2x = 180
2x = 180 - 50
2x = 130
x = 130/2
x = 65
Answer:
K=-2
Step-by-step explanation:
-3 = 5k + 7
Subtract 7 to the other side
-3 -7 = 5k
-10 = 5k
-2 = k
Start by dividing both sides by 3. Then take the square root of both sides. Then subtract 3 from both sides and divide by 2.
