Acute

Step-by-step explanation:

An obtuse angle is wider and more open than 90 degrees. acute angles are smaller than 90 degrees. Think of it like a book. If it looks like is half way open, it is acute. If it looks like it is almost completely open, it is obtuse. A right angle is 2 lines that make a 90 degree angle. Shown Below.

acute angle

Step-by-step explanation:

a straight angle is 180 degrees (a straight line) so its not a straight angle

a right angle has a 90 degree, this does not so its not a right angle

An obtuse angle has a measurement greater than 90 degrees, this does not,

so via process of elimination we know this is an acute angle

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
