.. Use the balanced hanger diagram to choose the equation that best represents how to find the mass of the triangle:
a. 2t + 21 = 5t + 12
b. 7t = 33
C. 2t + 24 = 5t + 13
d. 7t = 9

a

step-by-step explanation:

i would need to see the shape

step-by-step explanation:

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
