Answer:
x=12, y=30
Step-by-step explanation:
to find x:
in a equilateral triangle, all three sides are congruent, so:
4x-4=3x+8
x-4=8
x=12
to find y:
in an equilateral triangle, all the angles are 60°, so:
2y=60
y=30°
Check the picture below.
includes 2, notice, it doesn't go below 2 over the y-axis, and then it keeps on going up. So, the range is from +2 onwards.
Answer:
110
Step-by-step explanation:
Y and X have to equal 180
70+x+180
=110
Area = pi * 6^2 = 36*pi = 113.1 ft^2 to nearest tenth
