Answer:
???????
Step-by-step explanation:
triangles add to 180 degrees
lets call the unknown angle y
82 + x + y = 180
we also know that y + (2x-20 ) = 180 because it is a straight line
lets solve this for y
y + (2x-20 ) = 180
subtract (2x-20) from each side
y = 180 - (2x-20)
y = 180 - 2x + 20
y = 200 -2x
substitute this in the triangle equation
82 + x + y = 180
82 + x + 200 -2x = 180
combine like terms
282 -x = 180
subtract 282 from each side
-x = -102
multiply by -1 on each side
x = 102
the exterior angle is 2x-20
exterior angle is 2(102) -20
exterior angle is 204-20
exterior angle is 184
This is impossible.
There is a mistake with this problem
The triangle is not a triangle. Angle y would be negative. y=-4
Answer:
I believe the answer is B sorry if I'm wrong
Brigitte is shorter than 5 feet. (Brigitte's height=h)
We write this in inequality form
Brigitte's height is h
So 'h' is shorter than 5 feet
Shorter means less than so we use < symbol. We should not use = symbol because height is shorter than 5 not equal to 5.
Suppose if it is given ' height is more than 5 feet ' then we use greater than symbol (>)
h is less than 5 feet
h < 5
Inequality is h < 5
It should be |-80+15|=65 units because absolute value makes it positive.
Answer:
5/7
Step-by-step explanation:
Simplify by finding common factors and dividing both the numerator and denominator by it.
40/ 56 = 20/28(divided by 2) = 10 / 14 (divided by 2) = 5/7 ( divided by 2)
Hope this helps.
