All angles of a triangle added together equal 180 degrees
180=(6x-1)+(x+14)+(20) which simplifies to 180=7x+33
next, solve for x by subtracting 33
147=7x
then solve by dividing by 7
21=x
plug x back into your original equations to find the angle measures
A=6(21)-1 A=125 degrees
B=(21)+14 B=35 degrees
I think I know the answer but I’m not sure which point it’s asking for :(
Answer:
Ok ok, I see. So the answer is -9.
Step-by-step explanation:
We know the expresion is:
-3(-2+5)
We need to distrubute the -3 to what is in the parthese.
When I say distribute, basically you need to multiply the numbers inside the parethese by -3. So we can think of it as:
-3*-2=6
and:
-3*5=-15
Which we can rewrite as:
(6-15)
Subtract 15 from 6 and you get -9:
6-15=-9
Sorry hope this helps!
Answer:
Domain: -9, 5, 6, 4 Range: 4, 5, -1,
Step-by-step explanation:
The formula to find the area of a sector = Ф*r²/2
Ф to be in radian, here Ф=45° =π/4
sector = 1/2(π/4)x 100
sector = 39.27 ≈39.3° (B)
