we know angle RLP= 100⁰
also
angle RLP+ angle RLB=180⁰(Linear pair)
=>100⁰+angleRLB= 180⁰
=> angle RLB=80⁰
since BR and LR are equal, angle RBL and angle RLB are equal
therefore angle RBL is also equal to 80⁰
using angle sum property of triangles we know that the sum of all angles in a triangle is equal to 180⁰
=>angle BRL+angle RBL+angle RLB= 180⁰
=> angle BRL+80⁰+80⁰=180⁰
=>angle BRL = 180⁰-160⁰
=>angle BRL= 20⁰
I'm sorry it took me some time I'm a slow typer
Since it is 2 shirts
15 times 2 = 30
30% of off 30 dollars is 21 dollars
7% tax increase will come to 22.47
The total cost should be $22.47
Ok,
divide by 2 on both sides...
So X = 3/8!

Start with 12 stamps.
Divide this number by 3/4. This represents Carla giving 1/4 of the stamps to Thomas.
Multiply this number by 2. This represents Jim giving half of the stamps to Carla.
Multiply this number by 2. This represents John giving half of his stamps to Jim.
John started out with
64 stamps.
