Angle a is directly opposite from a 40 degree angle, so a=40. Then we can find b since the sum of the angles of all triangles is 180 and there is a right angle in there along with angle a:
Last, to find c we just notice that it is supplementary with an angle of measure 65, so:
So our angles are a=40, b=50, c=115.

Option B
Step-by-step explanation:
Lets open the brackets of L.H.S.
Lets substract q² from both the sides.
Lets divide both the sides by q.
Answer:
h = 1.403733341286
Step-by-step explanation:
17.
the triangle of sides ‘l’ and ‘l-h’ is a right angled triangle.
Then
Then
Then
18.
For l = 6 and θ = 40 :
= 6-6cos(40)
= 1.403733341286
