In a triangle, the three interior angles always add to 180°
m∠R + m∠S + m∠<span>T = 180
</span><span>(2x+10) + (2x+25) + (x-5) = 180
</span>2x+10 + 2x+25 + x-5 = 180
5x + 30 = 180
5x = 150
x = 30
0.3 is x but I can’t see the full problem so I’m nit sure what they are asking
Emily = x
Samantha = x + 2
Lauren = x + 4
x + (x + 2) + (x + 4) = 42
x = 12
Thus:
Emily = 12
Samantha = 14
Lauren = 16
Answer:
7.1 inches
Step-by-step explanation:
perimeter you go round from apointof your choice so
add 2+2=4
then apply 1/4πd for the round part
d=4 and it's quarter a circle then add them together
