Answer:
B. 16 degrees
Step-by-step explanation:
Because all of the angles in a triangle add up to 180 degrees, you can set up an equation for this problem:
2x - 10 + 4x + 46 + 3x = 180
Start by consolidating everything by adding like terms.
9x + 36 = 180
Then subtract 36 from both sides.
9x = 144
Then divide both sides by 9 to get your x.
x = 16
You first change the denominater to common and then you add the whole numbers and then the fractions 1 1/2 + 1 1/4 =1 2/4 +1 1/4+= 2 3/4
Answer:
5,000
Step-by-step explanation:
