Answer:
D. 77º
Step-by-step explanation:
Because 3 and 7 are corresponding angles and 3 = 77º, 7 also is 77º.
56 is the answer cause you use 7*8=56 so i hope that helps
Step-by-step explanation:
Let y1 and y2 be (e^x)/2, and (xe^x)/2 respectively.
The Wronskian of them functions be
W = (y1y2' - y1'y2)
y1 = (e^x)/2 = y1'
y2 = (xe^x)/2
y2' = (1/2)(x + 1)e^x
W = (1/4)(x + 1)e^(2x) - (1/4)xe^(2x)
= (1/4)(x + 1 - x)e^(2x)
W = (1/4)e^(2x)
Since the Wronskian ≠ 0, we conclude that functions are linearly independent, and hence, form a set of fundamental solutions.

Step-by-step explanation:
Henry is 15 years old.
Step-by-step explanation:
Let,
Henry's age = x
Henry's sister age = y
According to given statement;
y = x-3 Eqn 1
x*y=180 Eqn 2
Putting value of y from Eqn 1 in Eqn 2
Either,
x-15=0 => x=15
or,
x+12=0 => x=-12
As age cannot be negative, therefore,
Henry is 15 years old.
