Solve the equation: 8.7 + w = 5.1

-3.6

Step-by-step explanation:

if 8.7 +w=5.1  we will subtract 8.7 from both side and we will get

w= 5.1-8.7

w=-3.6

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
