Answer:
20 degrees F
Step-by-step explanation:
433.4
Height will be (14/2)/tan36 which is 9.63, then area for one triangle is 1/2*hb which is .5*9.63*7 is 43.34, times 10 you get 433.4
Answer x/3 -(-2)= 16
X/3+ 2=16
X/3=16-2
X/3=14
X= 14x3=42
subtract 4 on both side.
The required equation is 6x+5y+57=0.
