Answer:
90,45,45
Step-by-step explanation:
it a system of equations
say that x y and z are each angles of the triangle
that means that they add up to 180 so x+y+z=180
the question says that two of the angles in the triangle are equal so we can just say that x=y
and it says that the two angles that are the same length have a sum that is equal to the third side of the triangle which basically is x+y=z
x+y+z=180
x+y=z
x=y
we start with the first two equations:
since x+y=z then we can substitute z in for x+y in the first equation
z+z=180
2z=180
z=90
and since x=y then
x+x=z
2x=90
x=45
y=45
z=90
hope that helps :)

Answer:
Angle A:60
Angle B:120
AngleD:60
Angle E:60
Angle F:120
Angle G:120
Angle H:60
Step-by-step explanation:
There are supplementary angles that add up to get 180 so 120+ __=180
60 is the missing Angle of A and D and since the lines are parallel and we also have vertical angles. The angles are going to be either 120 or 60

find the area of triangle CDE the length of the square is 24 meters;
Answers
Answer:
288
Step-by-step explanation:
If you didnt know a triangle has the area of a square/2
so basically what im saying is the area of that square/2 equals the area of the triangle
to find the area of the square you take 24 and square it
24^2=576
finally we divide that by 2
576/2=288
so the area of the triangle is 288

The rectangular floor of a classroom is 40 feet in length and 32 feet in width. A scale
drawing of the floor has a length of 10 inches. What is the perimeter, in inches, of the
floor in the scale drawing?
Answers
The perimeter of the floor in the scale drawing is 36 inches.
What is the area of the rectangle?
To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.
The scale of the drawing is 10 inches for 40 feet, which means that every inch in the drawing represents 4 feet in reality.
To find the perimeter of the floor in the scale drawing, we can add up the length of each side in the drawing, where every inch represents 4 feet.
The length of the floor is 40 feet, which is equal to 10 inches in the scale drawing (40/4=10). So, the length of the scale drawing is 10 inches.
The width of the floor is 32 feet, which is equal to 8 inches in the scale drawing (32/4=8). So, the width of the scale drawing is 8 inches.
Therefore, the perimeter of the floor in the scale drawing is:
P = 2(length + width)
= 2(10 + 8)
= 2(18)
= 36 inches
hence, the perimeter of the floor in the scale drawing is 36 inches.
