Let’s solve where they have a triangle, so the height is 9 cm, the base is 3 cm:
1/2 • 9 • 3 = 13.5
Since there’s 2 triangles we do:
13.5(2) = 27
Now the rectangle in the middle, where the height is 9cm and the base is 12cm:
12 • 9 = 108
Add up the areas:
108 + 27 = 135
Answer:
A. 6 hours
B. No students studied for 6 hours
C. 4 students
(I’m just using a educated guess for B)
i’m not sure but try googling or looking on slader
As it is an equilateral traingle,
Each interior angle will be 180/3 = 60 degree
angle X, Y and Z are 60 degree
Angle W = 180 - 60 = 120 degree ( Linear Pair )
Now, the answers are :
A. w > y
B.w> x
C. y + z = w
E .x+ y = w
The rest Option D and F are incorrect because:
Option D
x + y =z
60 + 60 = 60
but 60 + 60 = 120
Option F
z> x
60>60
But 60 can not be greater than 60
The sign must be of equal ( = )
Answer: The triangle mentioned here is an acute angled triangle.
Step-by-step explanation: x+x+10+2x-6=180°(angle sum prop. of triangles)
= 4x+4=180°
= 4x=174°
= x=44°
therefore, x=<u>44°</u>
,x+10=44+10=<u>54°</u>
,2x-6=2(44)-6=<u>82°</u>
