Answer:
The value of x is 3.
Step-by-step explanation:
It is given that the angles of a triangle are 128, 5x+10 and 9x.
According to the angle sum property of a triangle, the sum of all interior angles of a triangle is 180 degrees.
Divide both sides by 14.
Therefore the value of x is 3.
-7 + 4(n-1). Use this and plug in 10 for n, making it
-7 + 4(9)
-7+36
29
By making y alone
3y-14=16
+14 +14
3y= 30
divide 3 on both sides
y=10
