Step-by-step explanation:
f(x) = 2^x (this is exponential function)
f(x) = 8
the equation is :
2^x = 8
2^x = 2³
cross out 2
so, we get : x= 3
Answer:
70 degrees.
Step-by-step explanation:
Hello!
It says that this triangle is a right triangle. That means one angle is 90°. Since there are 180° in a triangle, all we have to do is subtract 90 + 20 from 180.
90 + 20 = 110
180 - 110 = 70.
So the medium angle is 70°.
Hope this helps!
