Answer:
the third angle is 50 degress
Step-by-step explanation:
the angle sum property states that the sum of all the interior angles of a triangle is 180.
therefore : 30 + 100 + x = 180
x = 180 - 130
x = 50
It is a function. Every x value is different.

Make the variables:
x
x + 3
2x + 3 = 25
2x = 22
x = 11

Answer: 10
We can write,
1 3/4 as 7/4 & 3 1/2 as 7/2
So, 7/4 + 7/2 = 21 / 4 in fraction form.
OR 5 1/4 in mixed form.
