Congruent triangles method

AB/DB=BC/EC

10-x+x/10-x=3+2/3

10/10-x=5/3

30=50-5x

30-50=-5x

Answer:

$(\frac{6x^2y}{5})$

Step-by-step explanation:

Given

$\frac{(2x)(3x^3y^2)}{5x^2y}$

Required

Solve

Open the brackets

$\frac{(2x)(3x^3y^2)}{5x^2y}$ = $\frac{(2x*3x^3y^2)}{5x^2y}$

$\frac{(2x)(3x^3y^2)}{5x^2y}$ = $\frac{(6x^4y^2)}{5x^2y}$

Apply law of indices:

$\frac{(2x)(3x^3y^2)}{5x^2y}$ = $\frac{(6x^{4-2}y^{2-1})}{5}$

$\frac{(2x)(3x^3y^2)}{5x^2y}$ = $\frac{(6x^2y)}{5}$

$\frac{(2x)(3x^3y^2)}{5x^2y}$ = $(\frac{6x^2y}{5})$

Since the exponent is on the outside of the paranthesis, you'd have to multiply it by everything on the inside: a^m x b^m

Find the value of the lettered angles in each of the following ( see image ).

Arisa [49]

Step-by-step explanation:

here's the solution :-

1.) =》f = 90°

( because angle made by diameter on circumference of the circle measures 90° )

2.) =》here,

g + f + 56° = 180°

( because the sum of all interior angles of the triangle measures 180° )

=》g + 90° + 56° = 180°

=》g + 146° = 180°

=》g = 180° - 146°

=》g = 34°

3.) h = 56°

( since, they form alternate interior pair which are equal )
