Answer:
$312.30
Step-by-step explanation:
R=17.35(18)
R=312.30
Answer: y = 57°
Explanation: 180-114 = 66°
A triangle has a total of 180° so 180-66 = 114
114 / 2 = 57° (because angles y and y have the same value)
Hope this helps :)
Answer:
Length = 2x+y cm and since it's a rectangle,
2x+y=3x-y ---------------- (i)
width = 2x-3 cm
It's perimeter,
2(2x+y+2x-3)=120 ---------------- (ii)
Solving both equations,
x = 14 cm
y = 7 cm
so length is, 2×14+7 = 35 cm
and width is, 2×14-3 = 25 cm
so area will be, 35×25 = 875 cm²

To solve this, multiply both numbers (numerator/dominator) by 2. It is the same amount, just written differently.

This one is a little trickier. Find the fraction with the smallest dominator (bottom number) and multiply it by 2 to get 8. Then multiply the numerator (top number) by 2 as well. It ends up now being 6/8.
