In the right triangle ABC, ∠ C = 90 °, given a + B = 14, C = 10, find the right side length

In the right triangle ABC, ∠ C = 90 °, given a + B = 14, C = 10, find the right side length

Let a = x, B = 14-x,
A + B = C,
That is: x + 14-x = 100
The solution is: x = 6 or 8
Choose to fill in the question directly with Pythagorean number 6,8,10 on the line

If a + B = 14, C = 10, then the area of △ ABC is______ ．

∵ a + B = 14, C = 10, ∵ a + b) 2 = 196, that is, A2 + B2 + 2Ab = 196, and ∵ A2 + B2 = C2 = 100, ∵ 2Ab = 96, ∵ 12ab = 24, that is, s △ ABC = 24

Given the right side BC = AC of the right triangle ABC, and B (3,2). C (3, - 2), find the coordinates of point a and the area of △ ABC

A (- 1, - 2) or (- 1,2) or (7, - 2) or (7,2)
S△ABC=4×4÷2=8

In the triangle ABC, E.F is the point on AB AC, EF / / BC, the area of triangle EBC is 1, let x equal EF: BC, y is the area of triangle ABC, y and X function

Triangle BCE area: Triangle ECF area = BC * H / 2: (EF * H / 2) = BC: EF = 1 / x,
Because triangle EBC = 1, triangle EFC area = X
Area of quadrilateral befc = triangle BCE area + triangle EFC area
Quadrilateral efcb area = 1 + X
EF: BC = x
Area of triangle AEF: area of triangle ABC = X2,
Area of triangle AEF = area of triangle ABC - area of quadrilateral befc
So y - (1 + x) / y = x2
It is concluded that y = 1 / (1-x) x is not equal to 1

Tib2-32c10, TCL miniature circuit breaker, rated current is 10A = 30mA, wlm1 is leakage protection device, rated residual action current is 30mA, bv-5 * 6-sc32-cc (CT) conductor specification and laying method bv copper core PVC insulated wire 5 * 6 five conductors with 6 square mm cross section, sc32 welded steel pipe (inner diameter) 32mm

10 (BV (3 * 10) - sc25) - WS what does this electrical symbol mean

There should be 10 such circuits, each of which is 3 * 10 square mm and laid along the wall through 25 welded steel pipes

Bv-3x2.5 sr300x150 / pc15-we / WC / cc PJ = 0.8kw

This should be the circuit wiring line mode, line code, and construction method
BV is copper core PVC conductor, 3 pieces of 2.5 square,
I'm not sure about sr300x150 / PC15. It should be the requirement of pipe diameter and bend. PVC pipe diameter is 15mm
We / WC / cc means hidden along the wall and ceiling,
0.8kw is its power
Sorry, I only know about it. I don't know if I can help you
