Question

isosceles triangle
angle A=5X
Angle B=?
Angle C=2X
i need the value of B please can someone help me

Answer 1

$\huge \bold{ANSWER:-}$

let's take the b as y

then,

$a + b + c = 180°$

$5x + y + 2x = 180°$

$7x + y = 180°$

$y = 180 - 7x$

so the answer is :-

$\huge \red \star { \: b = 180 - 7x}$

Answer 2

Answer:

5x+X+2x=180

8x=180

X=180/8

X=22.5

B=X=22.5 cm

Step-by-step explanation:

A=5x=5×22.5=112.5

B=22.5

C=2x=2×22.5=45

112.5+22.5+45=180

B=22.5
