Answer:
18.5
Step-by-step explanation:
First find the area of the two triangles.
1.5 * 1.5 = 2.25
Find the area of the two top rectangles: 2.5 * 1.7 * 2 = 8.5
Finally, find the area of the floor: 1.5 * 2.5 = 3.75
2.25 + 8.5 + 7.75 = 18.5

The given statement "The exterior angles of a triangle are always obtuse." is not always true.
The given statement is "The exterior angles of a triangle are always obtuse."
We need to provide a counterexample to the given statement.
The angle is formed by a polygonalside and its extended neighbouring side. When a transversal cuts one of two lines, it creates an angle that is outside of the line.
Take an obtuse-angled triangle as a counter-example:
An obtuse-angled triangle or obtuse triangle is a type of triangle whose one of the vertex angles is bigger than 90°. An obtuse-angled triangle has one of its vertex angles as obtuse and other angles as acute angles i.e. if one of the angles measure more than 90°, then the sum of the other two angles is less than 90°.
In the figure given below, we can see in ΔABC, ∠A=110°.
Exterior angle to ∠A measures 70°.
Therefore, the given statement "The exterior angles of a triangle are always obtuse." is not always true.

Answer:
400
Explanation:
Assume that the number we are looking for is x
We know that:
60% of this number is 240
This means that:
60% * x = 240
0.6x = 240
x =
x = 400
Hope this helps :)
Answer:
30 degrees
Step-by-step explanation:
first you have to find angle TSU which is 70 degrees
you get this my doing 180 - 110
then you add up all the angles in the triangle
so, 80 plus 70
you get 150
then you do 180 - 150 and get 30 degrees
