Remark
This is an excellent question. Estimation is a powerful skill to have. People should always shop using estimates. Try it to see what happens.
x = 11.7 which rounds up to which we will call x1 and that is 12
y = 6.03 which round down to 6 which we will call y1 and that is 6
Now x - y = 5.67
If you do the rounded subtraction x1 - y1 = 12 - 6 = 6
The estimate is not zero. D is not correct.
There is enough information E is not the answer.
B is wrong, her estimate is larger than x - y
C is wrong the two subtractions are not equal.
A is correct and always will be no matter what numbers are chosen
A <<<< Answer
Given:
m∠ABC = 118°
m∠DAC = (9x - 33)°
m∠CAB = (2x + 7)°
To find:
The value of x.
Solution:
Sum of the adjacent angles in a parallelogram = 180°
m∠ABC + m∠CAB + m∠DAC = 180°
118° + 9x° - 33° + 2x° + 7° = 180°
92° + 11x° = 180°
Subtract 92° from both sides.
92° + 11x° - 92° = 180° - 92°
11x° = 88°
Divide by 11° on both sides.
x = 8
The value of x is 8.
Answer:
HJ>KJ>HK
Step-by-step explanation:
Side opposite to the largest angle is the largest.
Side opposite to smallest angle is the smallest.
ang K = 118° ang J = 28°
ang K + ang J + ang H = 180° (Sum of all the angles in the triangle is 180°)
118°+28°+angH=180° (Putting the values of ang K & ang J)
146°+angH=180°
ang H=180°-146°
ang H=34°
128°>34°>28°
ang K>ang H>ang J
Here, ang K is the largest, so the side opposite to it i.e. HJ will be the largest side.
Smaller than ang K and bigger than ang J is ang H, so the side opposite to it i.e. KJ will be smaller than HJ but bigger than HK.
Ang J is the smallest angle, so the side opposite to it i.e. HK will be the smallest.
HJ>KJ>HK.
