Answer:
x=54º
y=63º
Step-by-step explanation:
Let the other angle in the triangle be zº.
Because the measure of a line is 180º, zº=180º-117º=63º.
Because the triangle is isosceles yº=zº=63º.
The sum of the measure of the angles in a triangle is 180º. So, 63º+63º+xº=180º.
126º+xº=180º
xº=54º
Answer:
d= 24
Step-by-step explanation:
-2= d/3 - 10
-6= d-30
-d=-30+6
-d= -24
d= 24
Answer:
x = ± 2i
Step-by-step explanation:
note that 
= i
x² = - 12 ( take square root of both sides )
x = ± 
= ± 
= ± 2i
