Find the measures of the angles of each triangle (in degrees) and classify the triangle as acute/right/obtuse and scalene/isosce
les/equilateral (one from each triple)
A=5x - 10 B = 3x C= 2x - 10
1 answer:
Step-by-step explanation:
given :
A=5x - 10
B = 3x
C= 2x - 10
solution:
A+B+C = 180°
5x - 10 + 3x+ 2x - 10 = 180
10x -20 = 180
10x = 200
x = 20
A = 5(20)-10 = 100-10 = 90°
B = 3x = 3(20) = 60°
C = 2x-10 =2(20)-10 =40-10 = 30°
this is the right triangle and scalene triangle
