Answer:
Step-by-step explanation:
Let the unknown angle be x
As the interior angles in a triangle are added up to 180°
Hope this helps you.
Let me know if you have any other questions:-)
a= -5 , -2
b= 1 , 0
not sure if that helped sorry if i didnt
Answer:
In triangle ABC and triangle ADE
angle A = angle A (common)
anhle ABC = angle ADE
By AA , triangle ABC similar to triangle ADE
Thus
AB/AD = BC/DE
10/(10+x) = 6/10
60 + 6x = 100
6x = 40
x = 6.67

Answer:
- 1,563.5 in³
- 904.8 yd³
- 2,144.7 mm³
- 1,288.2 cm³
- 434.9 in³
Step-by-step explanation:
The formula for the volume of a sphere is ...
V = (4/3)πr³
When you have several of these calculations to do, it is convenient to let a graphing calculator or spreadsheet do them. A spreadsheet can do the rounding for you, too. The results are attached. The units are the cube of the units of the radius.
<u><em>Example calculation</em></u>:
(4) Radius = diameter/2 = 13.5 cm/2 = 6.75 cm
V = (4/3)π(6.75 cm)³ = 4.18879 × 307.547 cm³ = 1288.2 cm³
Note that the constant (4/3)π ≈ 4.18879 remains the same for each calculation. All you need to do is multiply that by the cube of the radius.
