250 cm³
the volume of a cuboid(V) = length × breadth × height
V = 5 × 10 × 25 1250 cm³
note 1 litre = 1000 cm³
empty space = 1250 - 1000 =250 cm³
140° + ∠5 = 180° <em>same side interior angles </em>⇒ ∠5 = 40°
∠2 ≅ ∠5 <em>vertical angles ⇒ </em>∠2 = 40°
∠8 = 53° <em>alternate interior angles</em>
∠3 ≅ ∠8 <em>vertical angles ⇒ </em>∠3 = 53°
x + ∠2 + ∠3 = 180° <em>triangle sum theorem</em>
x + 40° + 53° = 180°
x + 93° = 180°
x = 87°
Answer: 87°
Note: I just realized that there is an easier way to solve this:
∠9 + 53° + x = 180° <em>triangle sum theorem</em>
140° + ∠9 = 180° <em>supplementary angles </em>⇒ ∠9 = 40°
40° + 53° + x = 180°
x + 93° = 180°
x = 87°
Use whichever solutions makes sense to you.
Answer:
Step-by-step explanation:
Given the geometric sequence:
5, −10, 20, −40, ...
The first term is a = 5
And the common ratio = r = -10/5 = -2
The general rule of geometric sequence is
So, the rule for the given geometric sequence is:
The product of 12 and x.
hope this helped!
Iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii have noooooooooooo idea. good luck
