8. In a triangle, the three angles are: 60, 11x and 13x degrees. Find the value of x and plug it in to find the measure of the other two angles. Then classify
the triangle BASED ON ITS ANGLES. *

x=5

Step-by-step explanation:

60+11x+13x =180° (sum of angles in a triangle )

60+24x=180

24x=180-60

24x=120

x=120/24

x=5

Therefore the angles are 60, 55, 65

Which shows that it is a scaleness triangle and an acute angle

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
