The 3 inside angles of a triangle need to equal 180 degrees.
You are given 28 for one.
The second on is adding 58 + 77 = 135 degrees.
X = 180 - 28 - 135 = 17 degrees
Answer:
a = -2
b = 7
Step-by-step explanation:
5a+3b=11
-2a+3=b
substitute for b:
5a + 3(-2a + 3) = 11
5a -6a + 9 = 11
-a = 2
a = -2
b = 7
The angles remain the same. If you equally increase the lengths of the sides, the interior and exterior angles will not change. Both of them are similar to the original sign.
Answer:
The value of the expression at x=5 is 10
Step-by-step explanation:
The given expression is 
Let us simplify this expression.
Distribute -2 over the parentheses, we get

Now, substitute x = 5, we get

On simplifying, we get

The value of the expression at x=5 is 10
