29. Find the height of the trapezoid. Use this height to find the area. (A =

harkovskaia [24]

Answer:

The area of the trapezium is 168

Step-by-step explanation:

Area of a Trapezoid

Given a trapezoid of parallel bases b1 and b2, and height h, the area is calculated with the formula:

$\displaystyle A=\frac{b_1+b_2}{2}h$

The trapezoid in the figure has b1=15 and b2=27. We need to find the height. If we focus on triangle BCD, we can calculate the height as the distance EC by using the Pythagora's Theorem:

$10^2=EC^2+BC^2$

The side BC can be found as half the difference of the bases:

$BC=\frac{27-15}{2}=6$

Solving for EC:

$EC^2=10^2-6^2=100-36=64$

$EC=\sqrt{64}=8$

Now we have the height, calculate the area:

$\displaystyle A=\frac{15+27}{2}*8$

$\displaystyle A=\frac{42}{2}*8$

A = 168

The area of the trapezium is 168

Determine if the following pairs of lines are parallel, perpendicular, or neither (HINT: Look at slopes).

GarryVolchara [31]

Answer:

Neither

Step-by-step explanation:

The slopes are not opposite and they are not equal either

line up 2x+3y=42 and -3x +2y=16

2x+3y=42=-3x+2y=16

get each term on one side and isolate.

If this is not possible, you have your answer. Another way to do this is graphing it and seeing if the two lines intersect, and if they do, if they make a right angle
