How to construct angle 90 degrees ? Will mark brainliest

Mathematics

nata0808 [166]3 years ago
8 0

Answer:

We can construct a 90º angle either by bisecting a straight angle or using the following steps.

Step 1:  Draw the arm PA.

Step 2:  Place the point of the compass at P and draw an arc that cuts the arm at Q.

Step 3:  Place the point of the compass at Q and draw an arc of radius PQ that cuts the arc drawn in Step 2 at R.

Step 4:  With the point of the compass at R, draw an arc of radius PQ to cut the arc drawn in Step 2 at S.

Step 5:  With the point of the compass still at R, draw another arc of radius PQ near T as shown.

Step 6:  With the point of the compass at S, draw an arc of radius PQ to cut the arc drawn in step 5 at T.

Step 7:  Join T to P. The angle APT is 90º.

Hope this helps and good luck mate

Graph quadrilateral ABCD with vertices A(2,-3), B(3,5), C(6,6) and D(5,-3) and its image after the translation (x,y)→(x−5,y−2)
maria [59]

The graph can be drawn by the placing the points and after translation points becomes A'(-3, -5), B'(-2, 3), C'(1, 4), and D'(0, -5)

<h3>What is quadrilateral?</h3>

It is defined as the four-sided polygon in geometry having four edges and four corners.

We have:

Quadrilateral ABCD with vertices A(2,-3), B(3,5), C(6,6) and D(5,-3)

We can graph it on the coordinate plane as shown in the picture.

After applying the translation (x, y)→(x−5, y−2), the points becomes:

A'(-3, -5)

B'(-2, 3)

C'(1, 4)

D'(0, -5)

Similarly, we can graph it on the coordinate plane (refer attached picture)

Thus, the graph can be drawn by the placing the points and after translation points becomes A'(-3, -5), B'(-2, 3), C'(1, 4), and D'(0, -5)

In 1980, the average cost of a pack of cigarettes was $0.88. In 2000, the average cost was $5.31 per pack.
yan [13]

Answer:

The average rate of change of the cost of a pack is 22 cents per year.

Another name for the average <em>rate of change</em> is <em>slope</em>.

Step-by-step explanation:

The average rate of change of the cost of a pack (r), in monetary units per year, is equal to the change in the average cost of a pack (\Delta c), in monetary units, divided by the change in time (\Delta t), in years. Then, the average rate of change is:

r = \frac{\$\,5.31-\$\,0.88}{2000-1980}

r = \$\,0.22\,\frac{1}{yr}

The average rate of change of the cost of a pack is 22 cents per year.

Another name for the average <em>rate of change</em> is <em>slope</em>.
