If (a + 2) / 3 = (c + 5) / 6 = B / 4 and 2a-b + 3C = 21, try to find the values of a, B and C

(a+2)/3=b/4
2(a+2)=6b/4
2a=6b/4-4
b/4=(c+5)/6
18b/4=3c+15
3c=18b/4-15
2a-b+3c=6b/4-4-b+18b/4-15=5b-19=21
5b=40
b=8
c=7
a=4
a:b:c=4:8:7

Judge the prepositional phrase in this sentence
The rain fell in torrents.
Apart from the way of looking at the predicate verb, how can we judge that in torrents is not predicative?

In should be changed to into!
Falling is a process, and this process is not carried out in the torrent, but falls into the torrent, so it cannot be used in

In the triangle ABC, the angles BAC = 90 °, ab = AC, BD ⊥ Mn, CE ⊥ Mn, and the perpendicular feet are D and e respectively. If BD = 2cm, CE = 3cm, the length of De is calculated

Because BD ⊥ Mn, CE ⊥ Mn, so quadrilateral bfed is rectangular, then de = BF, EF = BD = 2cmcf = ce-ef = 1cm, because the angle BAC = 90 °, ab = AC, so triangle ABC is isosceles right triangle, so BC = radical 2 * AB, so BF = radical (BC ^ 2-bc ^ 2) de in right triangle BCF

Drawing with ruler and gauge: (do not write the method of drawing, but keep the trace of drawing, and mark with letters) known: ∠ 1 and ∠ 2 (as shown in the figure), calculate: ∠ AOB, so that ∠ AOB = 1 + 2

As shown in the figure: ∠ AOB is the required angle. (2 points will be deducted if no letter is marked)

If the length of the hypotenuse of a right triangle is 2 larger than that of the right triangle, and the other right triangle is 6, then the height of the hypotenuse is______ ．

Let a right edge be a, then the hypotenuse is a + 2, ∵ the length of the other right edge is 6, ∵ (a + 2) 2 = A2 + 62, the solution is a = 8, ∵ a + 2 = 8 + 2 = 10, the height of the hypotenuse is 8 × 6 △ 2 × 2 △ 10 = 24 × 2 △ 10 = 4.8
