5*4032=5*(4000+30+2)=5*4000+5*30+5*2, it helps to break down the number to smaller bits,
Answer: yes
Step-by-step explanation:
Lets look at side AC and BC.
BC = 10
AC = 15
10/15 = 2/3
Now side CE and CD.
CD = 8
CE = 12
8/12 = 2/3
SO YES!
Answer:
Step-by-step explanation:
13. All equilateral triangles are acute triangles. An equilateral triangle has three sides of equal length and three equal angles of 60.~ I think it is False.
14. If a triangle has two acute angles, then the third angle must also be acute.~ I think it is true.
15. A triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute. Therefore, an obtuse-angled triangle can never have a right angle; and vice versa. ~I think it is false.
