Answer:
the first one and the third one
Step-by-step explanation:
Answer:
x = -4 and x = 5
Step-by-step explanation:
Since 
and 
both equal to y, we know that the expressions equal to each other. We can write a new equation base on that.
Now we solve the equation.
3.9*10 = 39 then that to the 20 power is 6.626621133E31

Answer:
x = 17
Step-by-step explanation:
Hi there!
Because this is an isosceles triangle, we know that the angles measuring (x+17°) and (4x+34°) are congruent. Knowing this, we can set up the following equation and solve for <em>x</em>:
x+17 = 4x-34
17 = 3x-34
0 = 3x-51
3x = 51
x = 17
Therefore, the value of <em>x</em> is 17.
I hope this helps!
