obtuse angle is anything more than 90 degrees
Answer:
1.91h
Step-by-step explanation:
0.06h+h+0.85h
1.91h
We must look first for the properties given, so we have:
Rectangle - four sides, two pairs of opposite sides are parallel, four right anglesQuadrilateral - a four-sided figureRhombus - four sides, two pairs of opposite sides are parallel, all sides equal
So we're finding for a shape that has four sides that are all equal, with two pairs of parallel sides, and has four right angles. So from this description, we can say that it is a square. Squares have two pairs of parallel sides (like a rhombus and rectangle), four right angles (like rectangles), and four sides that are equal (like a rhombus). A square is also both a rectangle and a rhombus.
Solving for x is easier if
First, remove the parenthesis.
-3(x-1) = 3(4-x)-9
-3x + 3 = 12 - 3x - 9
Next, group the numbers with x on the left side and the rest on the right side.
-3x + 3x = 12 - 9 - 3
0 = 0
So, x has no solution.
