Answer:
18 square inches
Step-by-step explanation:
Surface Area of original prism: 54 square inches
Surface Area of similar prism:
1/3 x 54
=18 square inches
This relationship again shows that since w and y are perpendicular to each other that the smaller angles will add up to give 90 degrees.
3x + 3 + 15 = 90
3x + 18 = 90
3x = 90 - 18
3x = 72
X =72/3
X = 36 degrees
4:7=m:42
7*6=42
so multiply 4*6 also and m=24
or 4:7=24:42
Answer:
<u>y = x - 1/5</u>
Step-by-step explanation:
x - y = 1/5
5x - 5y = 1
5y = 5x - 1
<u>y = x - 1/5</u>
Answer:
Step-by-step explanation:
AC = AB + BC; BC = AC - AB
AC = 12 in
AB = 7 in
BC = 12 - 7
BC = 5
AB/BC = 7/5
