Answer:
Surface Area: 1090 inch²
Blue Paint needed: 545 inch²
Gold Paint needed: 545 inch²
Step-by-step explanation:
Is there a door or something? I'm assuming not because you didn't include it in your question.
Surface Area:
(7*15*2)+(15*20*2)+(20*7*2)=
210+600+280=
1090 inch²
If he paints half the doghouse blue and the other half gold then simply divide the surface area by 2:
1090÷2=545
He needs 545 inches² of blue paint
He needs 545 inches² of gold paint.

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°
