Answer:
x = 8
Step-by-step explanation:
( 6x + 1 ) + 90 + ( 5x + 1 ) = 180
6x + 1 + 90 + 5x + 1 = 180
11x = 88
x = 8
Break the parenthesis and distribute negative if needed but there are no negatives in front so we don’t have to do that. So we get 5b -9 + b + 8 So after combining like terms we get 6b -1
Answer:
C
Step-by-step explanation:
You can let y for the inverse
Like
X =5y - 11
Then you will get
X+11=5y
Then x+11/5=y
Answer: y = 5
Step-by-step explanation:
This triangle is isosceles.
So, ∠ABC = ∠ACB = 75°
Now,
sum of interior angles of a triangle = 180°
∠ABC + ∠ACB + ∠BAC = 180°
75° + 75° + (4y + 10)° = 180°
160° + 4y° = 180°
4y° = 20°
y = 5
You need to use the distance formula which is - <span>√(x1-x2)^2 + (y1-y2)^2
</span>fill it in with the given points - <span>√(4-2)^2 + (4-3)^2
simplify - </span><span>√2^2 + 1^2
</span><span>√4 + 1
</span><span>√5
so r = </span><span>√5
hope that helps :)
