You know that there is a right angle which equals 90 degrees, you take 90 + 67 +37 which equals 194. You have 2 x's so it should equal 2x. Then you take 194 divided by 2, and you should have the answer to what x equals
The surface area of a sphere by definition is given by:
A = 4 * π * r ^ 2
Where,
r: radius of the sphere.
Substituting the values we have:
294 = 4 * π * r ^ 2
We cleared the radio:
r ^ 2 = (294) / (4 * π)
Answer:
An equation that I could use to find the dome's radius is:
A. r2 = 294 square feet ÷ 4π

∠A = 36
∠C =36
∠ADB =72°
∠CBD =36°
∠BDC =108°
Explanation:
AB=AD then ∠ABD & ∠ADB must be equal as they share two lines that are equal so ∠ADB=72°
∠A and ∠C must also be equal (AB=BC)
∠A = 180-72-72=36°
So ∠A & ∠C=36°
∠D=180° (straight line)
So if ∠ADC=72
∠BDC=108° (180-72)
A triangle has 180° so in triangle BDC we have 108° and 36°
So remaining angle (∠CBD) =180-108-36
=36°
This tells us that triangle BDC is isosceles as it has two equal angles ∠CBD & ∠C =36°
