Answer:
1) 1.267x10^9
2) 2
Step-by-step explanation:
Answer: B = 1
Step-by-step explanation: The first step is to add 6 to both sides of the equation to get -2b = -2
You then divide both sides by negative 2 so you can get a positive
dividing both sides by negative 2 will leave you with 1b = 1
so
b = 1
Answer:
angle ACD= 138 degrees
Step-by-step explanation:
As angle W Z X is opposite to the angle CZD. Angle CZD is also 82 degree.
If we consider the triangle CZD the angle D is equal to 180 - 56 = 124 degrees.( angles on a straight line= 180)
The sum of the angles of a triangle is equal to 180 degrees
<C+<D +<Z= 180
<C= 180- 82-56
<C= 42 degrees
Since Angle DCZ= 42 degrees
angle ACD= 180-42 ( angles on a straight line)
angle ACD= 138 degrees
Check
angle ACD+Angle BDC+Angle ABD + angleCAB
138+ 56+124+42 = 360 degrees
