In ΔSTU, m∠S=(11x+3)∘,∠T=(2x+16)∘, and m∠U=(x+7)∘. Find .

frozen [14]

Answer:

x = 11

Step-by-step explanation:

In ΔSTU ,

m∠S = (11x+3)° ; m∠T = (2x+16)° ; m∠U = (x+7)°

According to angle sum property of a triangle , sum of all the interior angles of the triangle is 180°.

So,

$11x + 3 + 2x + 16 + x + 7 = 180$

$= > 14x + 26 = 180$

$= > 14x = 180 - 26 = 154$

$= > x = \frac{154}{14} = 11$

BRAINEST IF YOU GET THSI RIGHT

Scorpion4ik [409]

<h3>Solution :</h3>

$\sf \dfrac{6x+4}{3} = \dfrac{5x-5}{8}$

By cross multiply, we get

$\sf : \implies (6x+4) \times 8 = (5x-5) \times 3$

$\sf : \implies 48x+32 = 15x-15$

$\sf : \implies 48x+32 - 15x + 15= 0$

$\sf : \implies 33x + 47 = 0$

$\sf : \implies 33x = -47$

$\sf : \implies x = \dfrac{- 47}{33}$

Therefore, answer is $\sf x = \dfrac{- 47}{33}$
