1.When all the three cut outs of the angles A, B, C placed adjacent to each other at a point, then it forms a line forming a straight angle, i.e. 180°.

Flence, it is proved that the sum of the three angles of a triangle is 180°.

Therefore, ∠A + ∠B + ∠C =180

kifflom [539]

Answer:

V₂ = 450 cm³

Step-by-step explanation:

The volume of a gas V held at a constant temperature in a closed container varies inversely with its pressure P.

$V\propto \dfrac{1}{P}$

If V₁ = 600 cm³, P₁ = 300 mm hg, P₂ = 400 mm hg

We need to find a new volume. Using the above concept,

$V_1P_1=V_2P_2\\\\V_2=\dfrac{V_1P_1}{P_2}\\\\V_2=\dfrac{600\times 300}{400}\\\\V_2=450\ cm^3$

So, when the pressure is 400 mm hg, its volume is 450 cubic centimeters

Daniel [21]

$(x+5)>-1 or -(x+5)>-1$

$x>-1-5 or x$

$x>-6 or x$

This gives us the union of two sets

$(-∞,-4) U (-6,+∞)$

$=(-∞,+∞)$

x belongs to all real numbers
