Given that a trapezoid has the following dimensions, find the area. Area = ________ units2

1 answer:

8 0

The formula for the area of a trapezoid is A = a+b/2 * h. So just plug in the dimensions.
A = 5 + 3/2 * 5
A = 8/2 * 5
A = 4 * 5
A = 20 units²
I hope this helps love! :)

4. k/6 = 8/16 5. 5.4/7 = 27/h 6. 8/11 = 4/y+2

kupik [55]

Answer:

4. $k=3\\$

5. $h=35$

6. $\frac{7}{2}$ or 3.5

Step-by-step explanation:

$\frac{k}{6}=\frac{8}{16}$

Multiply those 2 values whose diagonal has both terms and divide by the term whose diagonal has the variable.

$k=\frac{8*6}{16}\\ k=\frac{48}{16}\\ k=3$

-----------------------------------------------------------------------

$\frac{5.4}{7}=\frac{27}{h}$

$h=\frac{7*27}{5.4} \\h=\frac{189}{5.4}\\ h=35$

-------------------------------------------------------------------------

$\frac{8}{11}=\frac{4}{y+2}$

$y+2=\frac{11*4}{8}\\ y=\frac{11*4}{8}-2\\y=\frac{44}{8}-2 \\y=\frac{11}{2}-2\\ y=\frac{11-2*2}{2}\\ y=\frac{11-4}{2}\\ y=\frac{7}{2}=3.5$

Find the measure of each angle. Assume the lines are parallel.

andreev551 [17]

Answer:

2 = 67

3 = 113

4 = 67

5 = 113

6 = 67

7 = 113

8 = 67

Step-by-step explanation:

opposite angle have to equal 180 because if you combine them they just become the line.

since the lines are parallel, measurements will be the same for the bottom set of angles as they are the top set of angles.

Help me please...........

gladu [14]

Answer:

Step-by-step explanation:

We require to find DC

ΔDEC and ΔBAC are similar triangles, hence the ratios of corresponding sides are equal, that is

$\frac{ED}{AB}$ = $\frac{DC}{BC}$ , that is

$\frac{11.5}{23.5}$ = $\frac{DC}{44}$ ( cross- multiply )

23.5DC = 506 ( divide both sides by 23.5 )

DC ≈ 21.532

distance travelled = BC + DC = 44 + 21.532 ≈ 65.5 in → C
