Step 1. Apply FOIL method. bb+b*2+8b+8*2
Step 2. bb+2b+8b+8*2
Step 3. Add similar elements. bb+10b+8*2
Step 4. Apply exponent rule. b^2+10b+8*2
Step 5. Multiply the numbers. b^2+10b+16
b^2+10b+16 is your answer.
Answer:
32
Step-by-step explanation:
First, one theorem states that (arc AB - arc AX) / 2 = angle ACB. We know that arc AB is 176, so we have
(176 - arc AX) /2 = ∠ACB
Next, the Inscribed Angle Theorem states that
arc AX/2 = ∠ABX
multiply both sides by 2
56 * 2 = arc AX = 112
Therefore, ∠ACB = (176-112)/2 = 64/2 = 32

Answer:</h2><h2>x=37.5° and angle ABC is 52.5°</h2><h2>
Step-by-step explanation:</h2>
We know that angle CBD is a right angle.
We also know that angle ABE is 180°.
Our unknown angle values are angle DBE and angle CBA.
angle CBD minus angle ABE will be 90°.
angle ABC plus angle DBE must equal 90°.
Solving for x:
(x+15)+(x)=90°
(x+15-15)+(x)=90°-15
(x)+(x)=75°
2x=75°
2x/2=75°/2
x=37.5°
Checking the work:
ABC=37.5°+15=52.5°
CBD=90°
DBE=37.5°
In conclusion, ABC plus CBD plus DBE equals 180°
