Answer:
In both cases, if the signs of the initial numbers are the same, the answer will be positive. If the signs are different, the answer will be negative
Step-by-step explanation:
Required
Signs of results of multiplication and division
If two non-zero numbers have the same sign, and they are multiplied together, the end result will be positive.
For instance:
2 and 4 are positive; so, 8 is positive
-2 and -4 are negative; so, 8 is positive
If two non-zero numbers have different signs, and they are multiplied together, the end result will be negative.
For instance:
-2 is negative, and 4 is positive; so, -8 is negative
2 is positive, and -4 is negative; so, -8 is negative
#a
m<5=40°
- Reason-Its Given
#b
m<2=140
- Reason-Given
#c
<5 and <2 are linear pair(looked properly in diagram) Hence they are supplementary.
#d
<5 and 2 are same side interior angles (Clearly shown on diagram .
- We can call them co responding interior angles and their sum will be 180 if lines are parallel
#e
a||b
Let's verify
Let the angle below <1 be <3
Now
<2+<3=180
<5+<4=180
- <5=<2
Hence verified
