Answer:
Step-by-step explanation:
for two angles x and y,
x and y are supplementary angles if they add up to 180°
i.e x + y = 180°
ANSWER: 18
EXPLANATION:
y=kxzw
where k is a constant
Making k the subject of the formula, we have
k=y/xzw
Inputting the values
k= 72/(2)(1)(12)
k=72/24
k = 3
Solving for y when x=1,z=2 and w=3
We have
y=kxzw
y = (3)(1)(2)(3)
y = 18
The answer is 18 I’m pretty certain so D
You cut out the question-
25
Square root of 25 is 5
