Use the image to complete the equation below

s2008m [1.1K]

Given:

A figure in which a transversal line intersect the two parallel lines.

To find:

The missing value for the equation $m\angle \_+m\angle BPD=180^\circ$

Solution:

In the given figure, the two parallel lines are line ED and line AB, and CD is the transversal line.

Angle BPC and angle BPD lie on a straight line CD. So,

$m\angle BPC+m\angle BPD=180^\circ$ (Supplementary angles)

Angle APD and angle BPD lie on a straight line AB. So,

$m\angle APD+m\angle BPD=180^\circ$ (Supplementary angles)

Therefore, the required complete equations are $m\angle BPC+m\angle BPD=180^\circ$ and $m\angle APD+m\angle BPD=180^\circ$ .

Suppose you have one pyramid with a base that is 10 meters long and 10 meters wide with a slant that is 15 meters. Now, if the l

Answer:

The difference between area of pyramids is 125 sq.m.

Step-by-step explanation:

Length of base = 10m

Breadth of base = 10 m

Slant height = 15 m

Area of pyramid = Area of 5 bases

Area of pyramid = $\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+10 \times 10$

Area of pyramid = 400 sq.m.

Now the length of base is increased to 15

Length of base = 15m

Breadth of base = 10 m

Slant height = 15 m

Area of pyramid = Area of 5 bases

Area of pyramid = $\frac{1}{2} \times 15 \times 15+\frac{1}{2} \times 15 \times 15+\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+10 \times 10$

Area of new pyramid = 525 sq.m.

Difference between area of pyramids=525 sq.m. - 400 sq.,. = 125 sq.m.

Hence The difference between area of pyramids is 125 sq.m.
