if they allowed him to build it...Plus that way he won't depress the rest of [little girl crying]

the visitors while building one of the windows for the funhouse

Claude finds that the window needs a diagonal brace to support it if the

corner of the window is at a right angle and the brace is at a 50 degree angle

from the bottom how many degrees from the side is the brace? all right so let's [Girl sitting at a table with a coffee]

think this through first things first let's label our angles the corner of the

window is a right angle so let's indicate that with a box in the corner

it's also good to keep in mind that right angles are 90 degrees in measure

the only other angle we know is from the bottom to the brace which is 50 degrees

we want to find the measure of the other angle since we don't know it yet let's

call it X to solve this we can use the idea of complementary angles or two [Two angles complementing each other]

angles whose measures add up to 90 degrees since X and the 50 degree angle

add up to 90 degrees we can find X by solving the equation X plus 50 equals 90

subtracting 50 from both sides gives us a value of 40 degrees for X feeling a

little less sad Claude goes on to build the floor he wants to make the door to [Claude appears with a hammer]

the funhouse tilted so that it's at an angle of 65 degrees

how tilted must the doorframe be in relation to the wall? Again we should

start by labeling our angles we know that the angle of the door is 65 degrees

and we'll call the other one X since we don't know it yet even though the door

frame is tilted the floor is still a straight angle since we know straight [Tilted door appears]

angles are 180 degrees in measure the two angles here are supplementary

angles or two angles whose measures add up to 180 degrees... since we know that two

angles add up to 180 degrees we can set the equation X plus 65 equals 180 and

solve for X so subtracting 65 from both sides gives us x equals 115 degrees as [65 subtracted from both angles]

our answer Claude has figured out all the angles in

his funhouse and building it has made him much happier he still has the

occasional relapse but he's cut down his sobbing sessions to only about once [Claude sobbing and the Joker appears]
