It is: 7.5+7.1+8.2 = 22.8 units.
It is 7.5 + 7.1 + 8.2 units of length.
Perimeter = 3*25 = 75 cm
The third angle measures 85⁰ (20 + 75 + 85 = 180) consequently, the triangle is an acute angled scalene triangle
Perimeter = 174cm (75 +75 +12 +12)
Using Pythagoras Theorem, 102 = (5√3)2 + L2 ( L is the length of the other leg of the triangle) 100 = 75 + L2 : L2 = 100 - 75 = 25 Then L = √25 = 5. The other leg measures 5 cm
Using the sine rule in trigonometry its area is 192.885 square cm and its perimeter is 65.379 cm both rounded to three decimal places.
Perimeter = 3*25 = 75 cm
The third angle measures 85⁰ (20 + 75 + 85 = 180) consequently, the triangle is an acute angled scalene triangle
acute-angled triangle
An acute angled scalene triangle.
There need not be any. There is no scale factor between a pentagon with a perimeter of 50 cm and a triangle with a perimeter of 75 cm. The shapes are totally different!The scale factor is 2 : 3.
It is an acute angled scalene triangle.
75% of 71= 75% * 71= 0.75 * 71= 53.25
The measures of the three exterior angles would be 95, 160 and 105.
15, 75 and 90 degrees.15, 75 and 90 degrees.
Perimeter = 174cm (75 +75 +12 +12)
An isosceles triangle has angles of 75, 75 and 30 degrees.
Using Pythagoras Theorem, 102 = (5√3)2 + L2 ( L is the length of the other leg of the triangle) 100 = 75 + L2 : L2 = 100 - 75 = 25 Then L = √25 = 5. The other leg measures 5 cm
