We know this angle is a 90° or a right angle. So another words we know adding these 2 expressions equals to 90°.
(4x + 3) + (x - 8) = 90°
Remove the parentheses and combine the like-terms:
5x - 5 = 90°
Add 5 on both sides:
5x = 95°
Divide 5 on both sides
x = 19
You answer is x = 19.

Answer:
Step-by-step explanation:
Hey, this question concerns the inscribed angle theorem.
The formula for this is:
∠ABC = 2*∠ADC
∴ ∠ABC = 40°
For proof, look up 'inscribed angle theorem (or central angle theorem)' on YT.
Actually, its not 4b + 5r its 4b +3r because look
step 1. 6b + 4r - (2b + r)
step 2. 6b + 4r - 2b - r
step 3. (6b - 26) + (4r - r)
step 4. 4b + 3r
So the answer is actually 4b + 3r
