Answer:

1/10

Step-by-step explanation:

There are three simple fractions in this problem: 3/5, -1/4 and 7/10. Rules of order require that the division (-1/4) divided by 7/10 be carried out first; the correct product is -10/28, or -5/14. Then we have 3/5 + (-5/14).

Here the LCD is 70. Then 3/5 + (-5/14) becomes 42/70 - 35/70, which simplifies to 1/10.

Answer:

∠G = 23.3

∠H = 42.8

∠J = 19.9

Step-by-step explanation:

Tan(G) = 0.43

=> G = Tan⁻¹(0.43)

=> ∠G = 23.3

Sin(H) = 0.68

=> H = Sin⁻¹(0.68)

=> ∠H = 42.8

Cos(J) = 0.94 

=> J = Cos⁻¹(0.94)

=> ∠J = 19.9

Hope this helps!
