Step-by-step explanation:
Given,
x = 81° and y = 41°
Also given in the figure that,
m∠AOB = x + y
Therefore, value of m∠AOB,
m∠AOB = x + y
= 81° + 41°
= <u>122° (Ans)</u>
44=p+p+6
1. 44=2p+6 combine like terms
2.38=2p subtract 6 from both sides
3. 19=p
4. the longer piece is 19+6=25 so 25inches
the other piece is 19 inches
The actual value = 25.7 ml
The error = 15.6%
This means that the value of error = 0.156 * 25.7 = 4.0092 ml
Now, the error percentage found means that the student got the value either greater than the actual one with the value of error or less than the actual one with the value of error.
This means that the two possible readings are:
either : 25.7 + 4.0092 = 29.7092 ml
or : 25.7 - 4.0092 = 21.6908 ml
Answer:
10x - 8 or 2( 5x - 4)
Step-by-step explanation:
Perimeter of a rectangle = 2( Length + Width)
<u>Rectangle A </u>
Length = x + 8,
Width = x - 1
<u>Rectangle B</u>
Length = 4x + 5
Width = 3x - 2
