All sides of an equilateral triangle are equal, so all three sides are 9 cm.
To find h, use the pythagorean theorem. This requires use of only one right triangle, where we use b as our h.
a^2+b^2=c^2
(4.5)^2+b^2=(9)^2
(20.25)+b^2=(81)
b^2=(81/20.25) or 4
square root both sides
b=2
To calculate the slope of any graph y = mx + b is usually used
Answer:
-12/3
Step-by-step explanation:
The formula to get slope is m=y1-y2 and x1-x2
REMEMBER SLOPE IS Y/X NOT X/Y
