Find the missing exterior angle X

Mathematics
1 answer:
mel-nik [20]3 years ago

Answer:

x=125°

Step-by-step explanation:

We know that the sum of angles in a quadrilateral is 360°

by subtracting 180 from the given angle measurements, we can determine that the interior angle next to x is equal to 55°

Then we subtract 55 from 180 to find that x=125°

Answer:

2/3(3/4x-3/2) = 1/2x-1

(2x+1) - (x+3/2) = x - 1/2

Step-by-step explanation:

1) Distribute 2/3 to both 3/4x and -3/2

2/3(3/4x) = 6/12x which can be simplified as 1/2x

2/3(-3/2) = -6/6 which simplifies to -1

2/3(3/4x-3/2) = 1/2x-1

2) (2x+1) - (x+3/2) combine like terms

2x-x = x

1 - 3/2= 1- 1 1/2 ( change 3/2 into an improper fraction. 2 goes into 3 one time with one left over. Place the “leftover” back on top of the original denominator of 2)

1- 1 1/2 = -1/2, so

(2x+1) - (x+3/2) = x - 1/2

vik wrote the equation 470 h equals 3,008 where h is the number of hours it took a plane flying at a constant speed of 470 miles
Hunter-Best [27]
As with any linear equation of this sort, divide by the coefficient of the variable.
.. 470 h = 3008
.. (470 h)/470 = 3008/470
.. h = 3008/470 = 6.4
