x=11
the angles are congruent so 6x-10=56
6x=66
x=11
Ew, mental math... so basically, we would estimate the washing dishes to 20 minutes, and cleaning 40 min,
together 20+40 min
is 60 minutes, aprox 1 hour
Shelly spent almost 1 hour cleaning
Answer:
B
Step-by-step explanation:
s>t because s is on top of the scale and t is below the scale
The sum of the angles of a triangle is 180°, then:
(x+40)°+(3x-17)°+(2x-5)°=180°
x+40+3x-17+2x-5=180
6x+18=180
6x=162
x=27°
