Answer:
C. opposite sides are parelell
Answer:
see explanation
Step-by-step explanation:
Given
tan a = =
We require the hypotenuse h
Using Pythagoras' identity
h² = 9² + 40² = 81 + 1600 = 1681 ( take square root of both sides )
h = = 41 , thus
sin a = =
cos a = =
Step-by-step explanation:
Factors of 72
= 2 x 36
= 2 x 2 x 18
= 2 x 2 x 2 x 9
= 2 x 2 x 2 x 3 x 3
Factors of 48
= 2 x 24
= 2 x 2 x 12
= 2 x 2 x 2 x 6
= 2 x 2 x 2 x 2 x 3
Common Factors = 2 x 2 x 2 x 3
HCF = 24
Ans : 24

Answer:
B
Step-by-step explanation:
sum of angles in a triangle is 180
6n +1 +108+9n-4=180
15n = 180 -105
15n = 75
n= 75/15 = 5
