The formula for finding the area of an equilateral triangle is
square root of 3 * (a^2/2)
a is the side length so in this case is 6
square root of 3 * (18)
the area is about 15.6
Answer:
or

Answer:
37+x+53 = 180
x=90
Step-by-step explanation:
To find x, we need to use the fact that a straight line equals 180 degrees.
37+x+53 = 180
Combining like terms
90+x = 180
Subtract 90 from each side
90-90+x = 180-90
x = 90
Answer: measure angle E= 88
Answer:x is 52 and y is 38.
Step-by-step explanation:
