It's an isosceles triangle, so the angles at the base are congruent:


m\anlge WXY=m\angle WZY


The triangle XYW is a rectangular triangle.


We know that the sum of the measures of angles in a triangle is 180°.


Therefore we have the equation:


m\angle YWZ+90^o+17^o=180^o\\\\m\angle YWZ+107^o=180^o\ \ \ |-107^o\\\\m\angle YWZ=73^o

Answer:

x = -7

Step-by-step explanation:

This is an exponential equation.

\frac{1}{2}^x=128

We need to take log(or ln) of both sides and use logarithm property to solve this.

So, let's take ln of both sides, so we have:

ln(\frac{1}{2}^x)=ln(128)

Now, we will use this property shown below to further simplify:

ln(a^b)=bln(a)

So, we now have:

ln(\frac{1}{2}^x)=ln(128)\\xln(\frac{1}{2})=ln(128)\\x=\frac{ln(128)}{ln(\frac{1}{2})}\\x=-7

The value of x is -7
