Answer:
3m / 7 = 7n / 3
49n = 9m
9m / 49n = 1
m / n = 49 / 9
Step-by-step explanation:
Answer:
Step-by-step explanation:
At = 2*(h×w + h×l + w×l)
= 2*(4.8×3.1 + 4.8×7.2 + 3.1×7.2)
= 2*(14.88 + 34.56 + 22.32)
= 2*71.76
= 143.52 cm²
Answer:
Given: , , , formed by two intersecting segments.
In the given figure;
Linear pair states that a pair adjacent angle formed when two lines intersect.
Then by definition of linear pairs,
and forms a linear pair
Also, and forms a linear pair.
Linear pair postulates states that the two angle that forms a linear pair are supplementary(i,e add up to 180 degree).
Then by linear pair postulates;
and
Substitution property of equality states that if x =y then, x can be substituted in for y or vice -versa.
then by substitution property of equality:
Addition property of equality states that:
if x =y, then x + z = y+ z
By addition property of equality:
hence proved!
