Answer:
x = 0
Step-by-step explanation:
2x + 161 = x + 46 + 115
Subtract x
x + 161 = 161
Subtract 161
x = 0
A triangle has 180 degrees as a whole. An obtuse angle is an angle that has more than 90 degrees while a right right angle has 90 degrees. So, if were to be added, it will give a result of more than 180 degrees. So, the only angle can be added to a triangle that has an obtuse angle is an acute angle, since an acute is an angle that has less than 90 degrees.
I believe it is a parallelogram.
Reasons:
1. It is a quadrilateral. Quadrilaterals have a total amount of 360 degrees. 80+100+100+80=360
2. It has oposite sides that are equal
3. If you look at a parallelogram it has two obtuse angles and two acute.
100= obtuse angle 80= acute angle
Because its not quite clear if the 5 is negative you might want to try once with a positive and once with it negative. anyway, when you only have multiplication like this, so no addition or subtraction, you can "distribute"the exponent on the outside of the parenthesis. so the first two terms become 8^(-2/3)(w^7)^(-2/3) hopefully you can figure out the rest. from here, with w if you have something to an exponent which is also to an exponent, you can multiply the exponents. so that's 7*(-2/3) which is-14/3. let me know if you have trouble with fraction multiplication. now negative exponents have something special about them. if you have a negative exponent you can write it as one over that term with a positive exponent. so the first term becomes 1/(8^(2/3)) which is 1/4.
