Answer:
2√61/19
Step-by-step explanation:
sin^2 x = 1 - cos^2 x
= 1 - (3√13/ 19)^2
= 1 - 117/361
= 244/361
sin x = √244/19
= 2√61/19.
The vlaue of z is 27°
Step-by-step explanation:
Given,
The angle is 63°
To find the value of z
We know that the diagonals of rhombus perpendicularly bisect each other.
Again,
z+63°+90° = 180° [ sum of all the triangle is 180°]
or, z = 27°
Answer:
$36 left
Step-by-step explanation:
42+37=79
115-79=36
First, we count how far reached the Nell:
3,5 * 16 = 56 miles
Secondly, we count how far reached the Kristin:
3,5 * 18 = 63 miles
Now we expect the difference in the distance between them:
63 - 56 = 7 miles
The results that Kristin about seven miles driven more than Nell.
