If a,b,c,d are in continuous proportion then prove that (c+a) (c+d) = (b+c) (b+d)

sesenic [268]

Answer:

We must prove that (c+a)(c+d) = (b+c)(b+d)

Let us use principles from mathematical induction
$\frac{a}{b} = \frac{b}{c} = \frac{c}{d} = x$
a=bx , b=cx, c=dx
a+c = b + c
c +d = b + d
Such that (a+c)(c+d)=(b+c)(b+d)

PLEASEE HELPP ME IM DESPERATE

Answer:

I can help with Q "4" as -

It uses triangle congruence test - here we use - SAS, as

one side is equal as it is given

both the angles are 90 degree

and they share a same side

so -

8x = 6x + 5

8x - 6x = 5

2x = 5

x = 2.5

RU = 6x+ 5 = 6 (2.5) + 5 = 20

( I am not so sure but I think this is the answer )

Answer: 5.196152423

Step-by-step explanation: Logically considering it's a Rhombus all the sides are equal to each other. So you just need to find the area. In this case you find the area by multiplying the sin of the given angle by the square root of the given side. So, 6²×sin (60)=6²×√3/2=31.17691454. After finding the area you then have to divide the area by it's base to find the height. So, 31.17691454 ÷ 6 = 5.196152423.

I didn't round any of the numbers. Hopefully this is correct.

Sorry about the messy diagrams (never been good at creating them) and how long it took.
