Question

Find the unknown angles in the given figure ​

Answer 1

Answer:

x= 40

2x-30=80-30=50........

Answer 2

Answer:

x = 40 and the other angle is 50

Step-by-step explanation:

By rule of straight lines, we know that the values of

x combined with 2x - 30 must be equal to 90. We can write this as an equation:

x + 2x - 30 = 90

We combine like terms to get

3x - 30 = 90

We add 30 to both sides to get

3x = 120

We divide both sides by 3 to get

x = 40

So, we know x = 40 and the other angle is 50.
