As the variation is direct we have:

Where,
k: proportionality constant
We must find the value of k.
For this we use the following data:
y is 18 when x is 5.
Substituting values we have:

From here, let's clear k:

Then, replacing values we have:

For x = 11 we have:
Answer:
An expression that can be used to find the value of y when x is 11 is:
When x = 11 we have:
Acute means that has 3 angles less than 90 degrees
obtuse means at lesat 1 angle is more than 90 degrees
right triangle means 1 angle=90 degrees
s we solve for thierd angle
all angles add to 180 so
35+45+x=180
80+x=180
subtract 80
x=100
100>90
obtuse angle is answer
Answer:
15
Step-by-step explanation:
if 6/10 = 9 gal. then we can divide 9 by 6 and then multiply that answer by ten
Answer:
b
