Answer:

45

Step-by-step explanation:

Let the number be X.

So 2/3 of a number would be (2/3)x and 1/5 of the same number would be (1/5)x.  Therefore, (2/3)x+(1/5)x=39.  Next, you combine like terms by converting the fractions: (10/15)x+(3/15)x=39.  Now, you add the fractions.  (13/15)x=39.  Lastly you divide both sides by 13/15 or multiply both sides by 15/13.  x=45.  That number would be 45.  

<u>If you would like to check</u>, you would do 2/3(45) or 90/3 which is 30 and do 1/5(45) or 45/5 which is 9.  30+9=39

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Gre4nikov [31]

Answer:

93° (to the nearest degree)

Step-by-step explanation:

sum of the interior angles of a triangle = 180°

Find angle C first, then subtract angle C and angle B from 180° to find angle A.

Use the sine rule \frac{sinA}{a}=\frac{sinB}{b}=\frac{sinC}{c} to find angle C:

Therefore,

              \frac{sinB}{b}=\frac{sinC}{c}

              \frac{sin38}{9}=\frac{sinC}{11}

         angle C = 48.80523914...°

Angle A = 180 - 38 - 48.80523914...°

              = 93.19476086..°

              = 93° (to the nearest degree)
