Answer:
A)72
Step-by-step explanation:
They have essentially divided up the line 2 different ways, into 2 parts and into 10 parts. The 2 parts is from 1 and 2 and then the 10 parts is because of the ratio 4-6. The 2 parts are not equal because one of them is 4 parts of the line and the other is 6, if we put that together we get the 10 equal parts of the line. A line is equal to 180 degrees meaning that we can divide that my 10 to figure out how much each part is equal to 180/10 is 18 so each of the 10 parts is equal to 18. We are looking for <1 which it says is equal to 4 parts so we will multiply 4 by 18 to get how much it is. 4 times 18 is 72 so the answer is A
I hope this helps and please don't hesitate to ask if there is anything still unclear!
Answer:
D 21
Step-by-step explanation: x/7 = 3

x = 21
Answer:
54 one-third acre lots
Step-by-step explanation:
24 - 6 = 18
18 ÷ 1/3 = 18 × 3 = 54
Answer:
Obtuse
Step-by-step explanation:
Use Pythagorian Theorm
c^2 = a^2 + b^2
c =hypotenus a= leg b= leg
57 is the largest side so its c and the others are a and b.
57^2 = 48^2 + 14^2
3249 = 2304 + 196
3249 > 2500
c^2 > a^2 + b^2 is obtuse
