Answer:
3m / 7 = 7n / 3
49n = 9m
9m / 49n = 1
m / n = 49 / 9
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
Step-by-step explanation:
The perimeter is about 14 units.
each triangle is half of a square. two triangles make a whole square.
It’s is 997/1000. Just put the number over the highest decimal place
Answer:
m = 10 , n = 5
Step-by-step explanation:
using the cosine and tangent ratio in the right triangle and the exact values
cos45° =
and tan45° = 1 , then
cos45° =
=
=
( cross- multiply )
m = 5
×
= 5 × 2 = 10
-----------------------------------------
tan45° =
=
= 1 , then
n = 5
