Answer:

Tổng 3 góc trong 1 tam giác là 180 độ

Vậy góc B = 180 - A - C = 180 - 90 - 50 = 40 độ

C là góc vuông -> C = 90 độ

Trong 1 tam giác, tổng 3 góc = 180 độ

-> Góc B = 180 - 90 - 50 = 40 độ

Construct a triangle ABC where BC =4cm ,B=60° and AB+AC=6cm

Fittoniya [83]

Answer:

Below is the step-by-step explanation.

Step-by-step explanation:

To determine:

Construct a triangle ABC

Information Fetching and Information Steps:

From the given data,

$BC\:=\:4\:cm$

$B=60^{\circ }$

$AB+AC=6\:cm$

Procedure:

First draw a line segment $BC\:=\:4\:cm$

Then construct angle of $m$ ∠ $60^{0}$ at $B$ on $BC$ .

Taking $B$ as center with $6\:cm$ radius, draw an arc which cuts the ray of $m$ ∠ $60^{0}$ at $X$ .

Then Join $X$ and $C$ .

The draw a perpendicular bisector of $XC$ .

Wherever this perpendicular bisector intersect $BX$ , name that point as $A$

Join $A$ and $C$ .

Thus, ∆ $ABC$ will be a required triangle.

Keywords: triangle, perpendicular bisector, angle

- If f ( x ) = x² + 2x - 1 and g ( x ) = 3x - 2 , then verify the following :

RideAnS [48]

Step-by-step explanation:

Hey there!

Given;

f ( x ) = x² + 2x - 1

g ( x ) = 3x - 2

To verify:

$( \frac{f}{g} )(2) = \frac{f(2)}{g(2)}$

LHS:

$(\frac{f}{g} )(x) = \frac{ {x}^{2} + 2x - 1}{3x - 2}$

~ Insert "2" instead of "x".

$(\frac{f}{g} )(2) = \frac{ {2}^{2} + 2 \times 2 - 1 }{3 \times 2 - 2}$

Simplify it;

$\frac{f}{g} (2) = \frac{4 + 4 - 1}{6 - 2}$

Therefore; (f/g)(2) = 7/4.

RHS:

$\frac{f(x)}{g(x)} = \frac{ {x}^{2} + 2x - 1}{3x - 2}$

~Insert "2" instead of"x".

$\frac{f(2)}{g(2)} = \frac{ {2}^{2} + 2 \times 2 - 1 }{3 \times 2 - 2}$

Simplify it.

$\frac{f(2)}{g(2)} = \frac{4 + 4 - 1}{6 - 2}$

Therefore, f(2)/g(2) = 7/4.

Since (f/g)(2) = f(2)/g(2) = 7/4.

Proved!

Hope it helps!
