Answer:
Only one triangle can be constructed.
Step-by-step explanation:
We are given two side lengths of a triangle of 10 cm and 8 cm. The angle between the sides of the triangle measures 40°.
With the above-given data only one unique triangle can be constructed.
And the length of the third side can be calculated using the property of triangle as
a² = 10² + 8² - 2 × 10 × 8 Cos 40° {Where a is the length of the third side}
⇒ a² = 41.43
⇒ a = 6.44 cm. (Answer)
Answer:
Step-by-step explanation:
first you add all the numbers together-
15+16+20=51
you add them up as shown-
=51
and the divide by 3, because you added up 3 numbers-
51/3=17
so your answer is 17
If the cylinder is closed at both ends the formula is
πdh + 2π(d/2)^2 where h = height and d = diameter
145-132= 13
13/145 = 0.089655 rounded to 9
