A trapezoid was broken into a rectangle and two equal

Mathematics

Step-by-step explanation:

For the base of the triangles, we just have to remove the 1m and divide the remaining measurement into two since they are symmetrical.

5m - 1m = 4m \\   \frac{4m}{2}  = 2m \: each

For the area of the rectangle:

base \times height = 1m \times 4m = 4 {m}^{2}

For the area of each triangle:

\frac{1}{2} base \times height =  \frac{1}{2} (2m)(4m) = 4m^{2}

For the area of the trapezoid, just combine the two areas:

4m² + 4m² = 8m²

Find the value of X

<h3>Answer:  112</h3>

=========================================================

Explanation:

The angle adjacent to the 146 degree angle is 180-146 = 34 degrees.

In other words, the angles 34 and 146 combine to 180. These angles are supplementary.

The tickmarks on this triangle tell us it is isosceles. The angles opposite the congruent sides are congruent angles. So the unmarked interior angles (not marked x) are 34 degrees each.

Now use the fact that any triangle has its interior angles always add to 180

x+34+34 = 180

x+68 = 180

x = 180-68

x = 112

If the product of two consecutive odd integers is decreased by one-third the lesser integer, the result is 150. find the integer
dlinn [17]
X(x+2)-(1/3)x=150
x²+2x-(1/3)x-150=0
x²+(5/3)x-150=0
3x²+5x-450=0
this does not produce an integer, because b²-2ac=5²+4*3*450=5425, and √5425=73.6546 is not an integer.
Please double check your question.
