17 + 2 = 19 km is 1/2 of the total length, that is,
19 = (1/2)h
(1/2)h = 19 multiply both sides by 2
h = 2*19
h = 38 km
The total length in kilometers is 38 km
Answer:
C. (1/2)acsinA
Step-by-step explanation:
Given is that, A, B, and C are the measures of the angles of a triangle and a, b, and c are the lengths of the sides opposite the corresponding angles.
So, the expression that does not represent the area of the triangle is :
C. (1/2)acsinA

Answer:
n= - 11/3
Step-by-step explanation:
3(n+8)=13
3n+24=13
3n=13-24
3n-11
n= - 11/3
Answer:
The correct option is B)
and 
Step-by-step explanation:
given 
Since, 
it means prependicular of right angled triangle can be calculated by pythagoras theorem as:
base² + prependicular² = hypoteneous²
2² + prependicular² = 3²
4 + prependicular² = 9
prependicular² = 9 - 4
prependicular² = 5
prependicular = √5
Since, 

Since, 

Hence, the correct option is B)
and
