The line perfectly cuts the 90 degree angle in half, as shown by the proportional x and y movement. Meaning that the angles are both 45 degrees
To solve this, plug 2b+1 in for a. :
4(2b+1)-5. Solve for b.
First use the distributive property:
8b+4-5=?
Combine like terms:
8b-1=?
Solve for b.
add 1 to both sides.
8b=1
Divide both sides by 8.
b=1/8
Answer:
it's an estimate within 10 degrees so I estimate that that angles is 5 degrees
Step-by-step explanation:
5 degrees
