svetoff [14.1K]

Answer:

x=25

Step-by-step explanation:

we know that

The triangle external angle theorem states that: An exterior angle of a triangle is equal to the sum of the opposite interior angles

In this problem

m∠9=m∠7+m∠8

substitute the given values

$(6x-20)\°=30\°+4x\°$

solve for x

$6x-4x=30+20\\2x=50\\x=25$
