Answer:
The Width of the Rectangle =
Step-by-step explanation:
The area of the rectangle
We are told that the width of the rectangle is equal to the greatest common monomial factor of
Let us determine the greatest common monomial factor of
Express each term as a product to pick out the common factors:
In the two terms, the common terms are 10 and . Therefore their greatest monomial factor =
The Width of the Rectangle =
Recall: Area of a Rectangle =Length X Width
Answer:
Using the Angle Addition Postulate, 20 + m∠DBC = 80. So, m∠DBC = 60° using the subtraction property of equality.
Step-by-step explanation:
If point D is the interior of angle ABC, then the angle addition postulate theory states that the sum of angle ABD and angle DBC is equals to angle ABC. The angle addition postulate is used to measure the resulting angle from two angles placed side by side.
From the attached image, ∠ABD and ∠DBC are placed side by side to form ∠ABC. Given that m∠ABD = 20° and m∠ABC = 80°
Hence, using angle addition postulate:
m∠ABD + m∠DBC = m∠ABC
20 + m∠DBC = 80
subtracting 20 from both sides (subtraction property of equality)
m∠DBC = 80 - 20
m∠DBC = 60°
