Answer:
x = 3
Hope this helps!
Step-by-step explanation:
ΔABC is a 45°, 45°, 90° triangle. The longest side ( 6 ) can be
while AB and CB are x. Because 6
is equal to
, you can see that x is equal to 6. Both AB and CB are equal to 6. ΔBDC ( CDB ) is a right triangle ( 30°, 60°, 90° ) so, BD = x, CB = 2x, and CD =
. CB is equal to 6 so 2x = 6, x = 3.
STEP - BY - STEP EXPLANATION
What to find?
The the value of secθ.
Given:
(4, 3)
⇒(x, y) = (4, 3)
Step 1
Draw a sketch.
Step 2
Substitute the values into the trig. ratio formula below.
From the sketch above, opposite = 3 and adjacent = 4
Step 3
Find the value of the hypotenuse side using Pythagoras theorem.
let h be the hypotenuse side.
Hence, hypotenuse = 5
Step 4
Substitute the values into the formula below:
But,
ANSWER
secθ= 5/4
tanθ=3/4
