The sum of the angles in any triangle is 180 degrees. If one of the three angles is 90 degrees (a right angle) the the sum of the other two angles is 90 degrees. Therefore each of the other two angles must be acute.
The statement is TRUE.
Answer:
Base = 126 cm or 60 cm
Step-by-step explanation:
Ratio of sides of isosceles triangle = 4 : 7
Sides are = 4x , 7x
If smallest sides of the isosceles triangle are equal, then
three sides are = 4x , 4x , 7x
Perimeter = 270 cm
4x + 4x + 7x = 270
15x = 270
x = 270/15
x = 18
Base = 7x = 7*18 = 126 cm
If largest sides of the isosceles triangle are equal, then
Three sides are = 7x , 7x , 4x
7x + 7x +4x = 270
18x = 270
x = 270/18
x = 15
Base = 4x = 4 * 15 = 60 cm
