Answer:
The Value of x is 10.
Step-by-step explanation:
Consider ABCD is a Parallelogram where
∠BCA = 43°
∠CBA = 98°
∠ACD = (2x+9)
To Find:
x = ?
Solution:
Triangle sum property:
In a Triangle sum of the measures of all the angles of a triangle is 180°.
In ΔABC
Now CD || BA .......opposite sides of Parallelogram is parallel
.........Alternate Angles are equal
Substituting the values we get
The Value of x is 10.
Answer:
x = 7
Explaination:
ABC = 40°
and BD bisects the angle so ABD = 20°
so 3x-1=20
solving for x gets us
x = 7
If Ann cleans in 12 hours then she cleans
of the apartment per hour. Similarly Liz cleans
of the appartment per hour. So together then can clean
of the apartment for hour. Therefor it will take them
hours to clean.
The general formula
can be used as a check if needed.

Step-by-step explanation:
Answer: triangle sum , x= 9
Step-by-step explanation:
The triangle angle sum theorem states that the 3 interior angles of a triangle sum to 180 degrees. Add all of the angle measures together and set equal to 180. (3x-4)+(5x-7)+(13x+2) = 180. Combine like terms. 21x -9 = 180. Add 9 to both sides. 21x= 189. Divide both sides by 21. X = 9
