In ΔJKL, j = 74 cm, k = 14 cm and l=80 cm. Find the measure of ∠J to the nearest degree.

natita [175]

Answer:

∠J = 60°

Step-by-step explanation:

The Law of Cosines tells you ...

j² = k² +l² -2kl·cos(J)

Solving for J gives ...

J = arccos((k² +l² -j²)/(2kl))

J = arccos((14² +80² -74²)/(2·14·80)) = arccos(1120/2240) = arccos(1/2)

J = 60°

Is 3/4 bigger than 11/16?

worty [1.4K]

Yes because if you simplify 11/16 you would not get 3/4. Or a bwtter way is if you times 4 by 4 to get 16 as a denominator, then multiply 3 by 4 it equals more than 11/16.

Simplify: ((x-5)3/2)^2/3 X-5 (x - 5)^2 (x – 5^)3

netineya [11]

Answer:

x - 5

Step-by-step explanation:

$((x - 5) {}^{ \frac{3}{2} } ) {}^{ \frac{2}{3} }$

$(x - 5) {}^{ \frac{3}{2} } { \times }^{ \frac{2}{3} }$

$(x - 5) {}^{ \frac{6}{6} }$

$(x - 5) {}^{1}$

Therefore x - 5
