Given:
m∠APB = 19°
To find:
The arc measure of DBC.
Solution:
∠APB and ∠DPC are vertical angles.
By vertical angle theorem:
m∠APB = m∠DPC
m∠DPC = 19°
DB is the diameter of the circle.
Angle measure of diameter = 180°
m∠DPB = 180°
m∠DPC + m∠CPB = m∠DPB
19° + m∠CPB = 180°
Subtract 19° from both sides.
19° + m∠CPB - 19° = 180° - 19°
m∠CPB = 161°
<em>The measure of central angle is equal to the measure of intercepted arc.</em>
m∠CPB = m(ar CPB)
m(ar CPB) = 161°
The arc measure of DBC is 161°.
Answer:
612 cm²
Step-by-step explanation:
Total surface area = area of all the nets in that make up the shape
✔️There are 2 equal rectangles of the following dimensions:
L = 10 cm
W = 4 cm
Area = 2(10*4) = 80 cm²
✔️There are 2 equal rectangles of the following dimensions:
L = 10 cm
W = 17 cm
Area = 2(10*17) = 340 cm²
✔️There are 2 equal rectangles of the following dimensions:
L = 4 cm
W = 17 cm
Area = 2(17*4) = 136 cm²
✅Total surface area = 80 + 340 + 136 = 612 cm²
Answer:
5 rolls
Step-by-step explanation:
If the perimeter around the square footage of the ceiling is equal to 12 + 12 + 12 + 12 = 48, even though the number is 48, in order to have all of the footage covered, Katie would need to buy (at least) 5 rolls.
