Question

i am asking this question 4th time
plz answer
​

Answer 1

Step-by-step explanation:

In an isoceles triangle we know base angles are equal [ since, opp angles of equal sides are also equal]

so ,

2x+7°=45°

2x= 38°

x=38°/2

x= 19°

Answer 2

Angle opposite to equal sides are equal so ,

$\angle \: y = \angle \: z$

$45\degree = 2x + 7 \degree$

$2x = 45 - 7$

$2x = 38$

$x = 19 \degree$

Now, using angle sum property (ASP)

$\angle \: x + \angle \: y + \angle \: z = 180 \degree$

$\implies \: 45 + 45 + \ \angle \: x = 180$

$\angle \: x = 90 \degree$
