Answer:
Option(1)
Step-by-step explanation:
By applying secant rule in the given right triangle,
secθ =
From the picture attached,
Opposite side of angle θ = 5 units
By applying Pythagoras theorem,
(Hypotenuse)² = (leg 1)² + (leg 2)²
= (10)² + 5²
= 125
Hypotenuse = √125
= 5√5
Now substitute these values in the expression of secθ,
secθ =
secθ = √5
Option (1) is the correct option.
4x + 2x = < y
This is because the opposite sides (which is 4x and 2x) of a triangle add up to the exterior angle (<y).
We have to find X.
As you know:
because the angles of a triangle add up to 180.
When we add them:
The 9 is multiplying with the X. We want X only and not 9 with it. So, when we take 9 to the other side, it becomes divide. As a result, the answer to x is:-
Substitute value of x into 4x and 2x to find the exterior angle:-
4x:
2x:
When we add them we get the answer for angle Y:-
Therefore, we can conclude that:
