Answer:
4/5
Step-by-step explanation:
Given :
- A right angled triangle with sides 24 , 3 and 40 .
And we need to find the value of sinZ .
We know that , sine is the ratio of perpendicular and Hypotenuse. So that ,
sinZ = p/h
sin Z = 32/40
sin Z = 4/5
<u>Hence the renquired answer is 4/5.</u>
The plane has intercepts at (1, 0, 0), (0, 2, 0), and (0, 0, 6), so we can parameterize the surface

by


where

and

. Now

so the surface integral reduces to
Answer:
B
Step-by-step explanation:
The sum of the 3 interior angles of a triangle = 180°
Check the sums of the given sets of angles
90° + 42° +58° = 190° ≠ 180° ← not valid
60° + 60° + 60° = 180° ← Valid
100° + 48° + 42° = 190° ← not valid
31° + 75° + 70° = 176° ← not valid
The answer TO THE QUESTION WILL BE D
