Prove that the curve a(t) = (cost, sin 2t, cos 2t) is regular on r and that it self-intersects at (1,0,1). check the self-intersection part by using algebra and also by using geofte

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130

320ft

step-by-step explanation:

120 divided by 3 equals 40

40 times 4=160

160 times 2=320

i think it's b. 5.5

step-by-step explanation:

because if you subtract 2 from 7.5 that's what you

hope that . i might be wrong though =i
