3x - 20 + 3x + 5 = 111

Combine like terms
6x - 15 = 111

Add 15 to each side.

Evaluate
6x = 126
x = 21

Plug x back into the equation for angle EFG.
EFG = 3x -20
3(21) - 20
EFG = 43 degrees

Answer:

$m\angle EFG =43\degree$

Step-by-step explanation:

$m\angle EFG +m\angle GFH = m\angle EFH\\\\(3x-20)\degree + (3x+5)\degree =111\degree \\\\(3x-20+3x +5)\degree =111\degree \\\\(6x-15)\degree =111\degree \\\\(6x-15) =111 \\\\6x = 111 + 15\\\\6x = 126\\\\x = \frac{126}{6}\\\\x = 21\\\\m\angle EFG = (3x-20)\degree\\\\m\angle EFG = (3\times 21-20)\degree\\\\m\angle EFG = (63-20)\degree\\\\m\angle EFG =43\degree\\$

Answer:

(3 + 2x) + (4 – 5x) = 7 - 3x

(3 + 2i) + (4 – 5i) = 7 - 3i

Step-by-step explanation:

In the addition of two binomials you have to add separately each monomial as follows:

(3 + 2x) + (4 – 5x) =

= (3 + 4) + (2x - 5x) =

= 7 - 3x

Analogously, the sum of the complex numbers 3 + 2i and 4 – 5i is made adding the two real parts from one side, and the two imaginary parts from the other side, as follows:

(3 + 2i) + (4 – 5i) =

= (3 + 4) + (2i - 5i) =

= 7 - 3i
