This is true. In order to get an obtuse triangle, one angle must be greater than 90 degrees because the definition of an obtuse triangle is an angle measuring greater than the right angle. The other angles must be less than 90 degrees because the sum of the angles must be 180 degrees.
Y -:5 = 2/3x + 6 because 6 is 2/3 of 9
add 5 to both sides
y - 5 +:5 = 2/3x + 6 + 5
y = 2/3x + 11
the y intersept is 11 or (0 , 11) when x is 0
when x is 3
y = 2/3 (3) + 11 or 2 + 11 = 13
so a 2nd point could be (3 , 13)
Answer:
Area = 90 units^2
Step-by-step explanation:
For the area of a triangle, we can simply use the following equation:
Area = ( 1 / 2 ) * Base * Height
We are given a base of 12 and a height of 15, so we can simply plug those values into the formula to find the area.
Area = ( 1 / 2 ) * Base * Height
Area = ( 1 / 2 ) * 12 * 15
Area = 6 * 15
Area = 90
Hence, the area of our triangle is 90 units^2.
