Answer:
A = 60 and B = 30
Now, A + B = 60 + 30 = 90
Also, A – B = 60 – 30 = 30
sin (A + B) = sin 90 = 1
sin A cos B + cos A sin B = sin 60 cos 30 + cos 60 sin 30
Answer:
The curve represented by Green color Dotted Lines in the attached figure represents the Reflection in x-axis of the curve 
.
Step-by-step explanation:
As we know, the value of 
lies between (-1,1) and its graph is a curve. Its value keeps on varying between -1 and 1 only depending on the value of 
.
The value of 
is 
at 
. Few values are labeled in the figure attached in the answer. The value is 1 at 
.
The curve shown in blue color solid line represents the curve of .
And the curve shown in the dotted green color in the attached figure represents the reflection in the x-axis.
We can simply add the expression to simplify the expression. So,
(7+3i)+(-8+9i) =7 +3i -8+9i Get rid of paranthesis.
=(7-8)+(3i+9i) Group the like terms.
= -1 + 12i
Answer:
Yes
Step-by-step explanation:
Answer: ~27.5
Step-by-step explanation:
I don't know about all the geometry terms, but since a line is 180°, and SE makes 1 right angle (90°), the other side is also 90° (180-90=90).
This means you have a right triangle with sides 15 and 23 and unknown hypotenuse AS.
Pythagorean Theorem: a^2 + b^2 = c^2
(15^2) + (23^2) = AS^2
sqrt( 225 + 529 ) = AS
AS = 27.459
