In ΔABC, m∠A = (3x + 8)°, m∠B = (2x + 7)°, and m∠C = (x – 9)°. What is the value of x?

emmasim [6.3K]

Answer:

x = 29

Step-by-step explanation:

In problems like these all you have to do is simply add up all the xs and set them equal to 180

3x+8+2x+7+x-9=180

6x+6+180

2 left-bracket (12 + 2 x) + (15 + 2 x) right-bracket = 74<br> Help me

Ainat [17]

Answer: $x=\frac{5}{2}$

Step-by-step explanation:

Do you mean $2[(12+2x)+(15+2x)]=74$ ? In that case just finish things inside the bracket first then multiply 2 inside.

$2(12+2x+15+2x)=74$

$2(27+4x)=74$

Then multiply 2 inside the bracket.

$54+8x=74$

Move 54 to other side then we get,

$8x=74-54$

$8x=20$

$x=\frac{20}{8}$

$x=\frac{5}{2}$

(Note: If this is not what you mean then please let me know.)
