Answer: A compound inequality contains at least two inequalities that are separated by either "and" or "or". The graph of a compound inequality with an "and" represents the intersection of the graph of the inequalities. A number is a solution to the compound inequality if the number is a solution to both inequalities.
Answer:
x=-10
Step-by-step explanation:
since there's a given 120 degrees, and it's a isosceles triangle, we know that the line adds up to 180 (where the 120 degrees is). so 120+x=180, the interior angle measures 60 degrees. That being said, the 3 angles measure 60 degrees also. now there's a right angle mark on top, so we find the angle of the smaller triangle (near angle 2) by doing 90-60=30 degrees.
angle 2 is said to be x+160, and there's a line, which tells us that they must add to 180.. so x+160+30=180
x+190=180
x=-10.
The formula for surface area of a triangular prism is
SA = 2(L)(W) + 2(W)(H) + 2(H)(L) * 1/2
SA = 2(3)(2) + 2(2)(4) + 2(4)(3) * 1/2
SA = 12 + 16 + 24 * 1/2
SA = 52 *1/2
SA= 26sq in
I hope this helped!:)
