2/8
Step-by-step explanation:
Answer: x > 2
Step-by-step explanation:
First, you need to isolate the variable by subtracting each side by 15.
4x + 15 > 23
-15 -15
= 4x > 8
To get the value for the variable, divide each side by 4.
4x/4 = x 8/2 = 2
x>2
In any right triangle ABC, with right angle A we have the following:

and

.
This means that the sine of a non 90° angle, is equal to the cosine of its complementary angle.
Thus,

.
(Take a look at the picture. From the definition of trigonometric ratios in right triangles we have :

and

)
Answer: 19/20
A = 30n - 40 I hope that’s correct
