Given:
Right triangle
To find:
The six trigonometric functions of θ
Solution:
Hypotenuse = 18
Adjacent side to θ = 10
Opposite side to θ = ?
Using Pythagoras theorem:



Subtract 100 from both sides.

Taking square root on both sides.

Using trigonometric ratio formula:












Answer:
C
Step-by-step explanation:
Since the triangle is right with hypotenuse QR
Use Pythagoras' identity to solve for QR
The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is
QR² = 8² + (8
)²
= 64 + 192
= 256 ( take the square root of both sides )
QR =
= 16
It’s D because the number that have an (x) is a COEFFICIENT and I hope it helps :)
The answer is (-2, -3) since 2*-2–(+)3= -1 and 2*-2-4*-3= 8.
D. Three less than five times the quantity of a number plus two.
