Answer:
Step-by-step explanation:
1. 30 degrees (vertical angles)
2. 60 degrees (complementary angles)
3. 150 degrees (supplementary angles and vertical angles)
4. 90 degrees (complementary angles)
The equation to find a spheres surface area is 4 pi R ^2
and this works in any order
4 * 12 is 48 (4 * R)
48^2 is 2304 ((4 * R)^2)
the exact answer is 2304

the full answer is 7234.56 (((4 * R)^2)

)

Answer:
A x = 15
Step-by-step explanation:
Lines AB and CD being perpendicular means the angles where they meet are all 90°. The diagonal line divides two of those 90° angles into two parts (each). The whole (90°) is the sum of the parts into which the angle has been divided.
The sum of angles 3 and 4 is 90°. Once you understand this relationship, you can write an equation based on the relationship. The equation can be solved in the usual way.
(4x +4)° +26° = 90°
4x = 60 . . . . . . . . . . . . divide by °, subtract 30
x = 15 . . . . . . . . . . divide by 4
