Answer:
a=8
Step-by-step explanation:
-5(a+3)=-55
First you times the bracket by -5
-5a-15=-55
Then you add the 15 to -55 because since the 15 is a negative on the right it has to be the opposite to the left
-5a=-40
Then you divide both sides by negative 5
-5a . = . -40
--------- ----------
- 5 -5
a= 8
The sine of the angle = the length of the opposite side. the length of the hypotenuse.
The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
The tangent of the angle = the length of the opposite side. the length of the adjacent side.
