Answer:
The measure of the largest interior angle is 
.
Step-by-step explanation:
Given one of the interior angles of the triangle = 40°. Let the other interior angles be represented by b and c.
Sum of angles in a triangle is 
.
So that;
b + c + 40° =
b + c = - 40°
b + c = 
But, b and c are in the ratio 3:5
Thus,
b = 
x
= 
b =
c = 
x
=
c =

The measure of the largest interior angle is .
The walls are vertical so the angle opposite X would be a right angle which is 90 degrees.
X would be 180 - 90 - 35 = 55 degrees
X and 2y - 5 are complementary angles which add together to equal 90:
2y - 5 + 55 = 90
Simplify:
2y +50 = 90
Subtract 50 from both sides:
2y = 40
Divide both sides by 2:
y = 20
200 +6m = 500-6m
add 6m to each side
200+12m = 500
subtract 200 from each side
12m = 300
divide both sides by 12
m = 300/12 = 25
25 minutes
check:
200+ 25*6 = 200 +150 = 350
500 - 25*6 = 500-150 = 350
Hello there!
f(x)=x
f(x) is also known as y
x is 3, which means the x value on the right is 3
Answer: f(3)=3
