Answer:
the answer would be the first one 321 m^2
Step-by-step explanation:
m=2(wl+hl+hw)=2·(10·6+6·6+6·10)=312
If you have
2 KNOWN sides & 1 Angle ;
Use Cosine Rule
If you have 3 KNOWN sides,
Also Cosine Rule
If you have
2 KNOWN angles & 1 side,
Use SINE rule
If it's a right-angled triangle, use SOH CAH TOA
Hopefully this helps
Answer:
Step-by-step explanation:
Let the volumes of both the spheres be
and their radii be
respectively.
(given)

From equations (1) & (2), we have:
Thus, the ratio of the volumes of two spheres would be 2197 : 729.
Given that
∠ABC and ∠CBD are complementary
Sum of complementary angle = 90°
⇒ m∠ABC + m∠CBD = 90°
⇒ 25° + m∠CBD = 90° [ Given that m∠ABC = 25°]
⇒ m∠CBD = 90° - 25°
⇒ m∠CBD = 65°
Hence proved
