Answer:

s = 30

Step-by-step explanation:

the total angle is a straight angle that's composed of a right angle and 2 unknown angles.

straight angle = 180°
right angle = 90°

(s + 1) + 90 + (2s- 1) = 180

s + 2s + 90 + 1 - 1 = 180

3s = 180 - 90

3s = 90

s = 90/ 3

s = 30

Find the value of x, for which : (81) -4 ÷ (729) 2-x = 9 /4x

tamaranim1 [39]

Answer:

$\huge{x = \frac{236164}{9477} = 24 \frac{8716}{9477}}$

Step-by-step explanation:

$(81) - 4 \div (729)2 - x = \frac{9}{4} x$

$81 - \frac{4}{729} \times 2 - x = \frac{9}{4} x$

$81 - \frac{8}{729} - x = \frac{9}{4} x$

$\frac{59041}{729} - x = \frac{9}{4} x$

$236164 - 2916x = 6561x$

$- 2916x - 6561x = - 236164$

$- 9477x = - 236164$

$\boxed{\green{x = \frac{236164}{9477} = 24 \frac{8716}{9477}}}$
