To solve this question, we have to set up a proportion that relates the two triangles.

In the bigger triangle, the bottom piece equals 30 feet.
In the smaller triangle, the bottom piece equals 5 feet.

In the bigger triangle, the height equals x feet.
In the smaller triangle, the height equals 30 feet.

In a proportion, this would be:

5/30 = 30/x

To solve this proportion, we can use cross-products, or setting the products of the opposite numerators and denominators equal to each other.

5 * x = 30 * 30

Now we have to simplify both sides of the equation by completing the multiplication operations.

5x = 900

Finally, we must divide both sides by 5, to get the variable x alone on the left side of the equation (get rid of coefficient of 5)

x = 180

Therefore, x = 180 or the height of the bigger triangle (building) is 180 feet.

Answer from: Quest

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

Answer from: Quest

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
