Answer:
b-3x+19
Step-by-step explanation:
you have to open the bracket so 3*x=3x
3*3=9
therefore;3x+9+10=3x+19
Accounting is an action of financial accounts, the target audience is people who want to major in business/accounting.
Answer:
D) 20°
Step-by-step explanation:
Using the triangle sum theorem, you know that every triangle's interior angles add up to 180°. Therefore the bottom triangle's missing angle can be found by giving it the variable x.
57° + 30° + x = 180°
Simplify: 87° + x =180°
x=93°
By the vertical angles theorem, the vertical angle directly across this angle is congruent to this one. Meaning that the top triangle's angle are 67°, 93°, and unknown, which we can assign y. We can use the same method from above here.
67° + 93° + y = 180°
Simplify: 160° + y = 180°
y=20°
Answer:
18.84
Step-by-step explanation:
Since the formula for circumference is
, we need to first find the radius. The formula for the radius is
, so we will get
. Substitute that into
, and we get
. Hope this helps!
