Answer:
The answer to your question is sin Ф = 4/5
Step-by-step explanation:
From the picture, we know that ∠C is a right angle, so ΔABC is a right triangle.
To solve this question use trigonometric functions
sin Ф = Opposite side / hypotenuse
Opposite side = 4
Hypotenuse = 5
Then,
sin Ф = 4/5
Answer:
C.
Step-by-step explanation:
Since both terms are perfect squares, factor using the difference of squares formula to get you the answer
(7x+9)(7x-9)
The value of x will be 23
Answer:
d=13.8
Step-by-step explanation:
secant-secant theorem: (a+b)b=(c+d)d
(14+20)14=(16+d)16
34*14=256+16d
476=256+16d
220=16d
d=13.75
