153 1/2 I thinkOr you have to convert it Good luck
Answer:
48
Step-by-step explanation:
let s be the snowman, g be the girl, and t be the christmas tree
2s+g=24
2t+2ts=132
3t+2g=26
subtract 2 times the first equation from the third one to get
3t-4s=-22
from the second equation we can deduce
2t(1+s)=132
t(1+s)=66
t=66/(1+s)
Substitute:
3(66)/(1+s)-4s=-22
3(66)/(1+s)=4s-22
3(66)=(4s-22)(1+s)
3(66)=-18s+4s^2-22
4s^2-18s-220=0
using the quadratic formula, we get s = 10, s = -5.5.
2(10)+g=24
g=4
2t(1+10)=132
2t=12
t=6
So 2s+t*g= 20+6*4=48
you would get a different solution for the negative s, but since snowmen cannot be negative, 48 is the answe.r
Atrap=(a+b)/2*h a=base 1 b=base 2 c=height
The third angle of triangle RST is 180-38-75 = 67
<span>which is one of the given angle of the second triangle. </span>
<span>So both triangles have the same angles and the sides are proportional. </span>
<span>The two triangles are similar, therefore one is a dilation of the other.</span>
