Answer:
∠2 = 152
Step-by-step explanation:
A straight angle should always equal 180, and that is really the key to how we answer this problem. That means that ∠1 and ∠2 are supplementary, and add up to 180°.
That means that 180-28, will give us our other angle.
Answer:
x= 3
Step-by-step explanation:
Simplify the equation:
3(2x-5)- 4x+8= -1 becomes 6x-15-4x+8= -1
Then, combine like terms.
6x-4x= 2x
-15+8= -7
So now your equation becomes 2x-7= -1
Now, we need to isolate our variable (x).
Add 7 to both sides.
-7+7 cancels out and -1+7= 6
and now you have 2x=6
To solve for x, you need to divide by 2 on both sides and you get an answer of 3.
x= 3
