What do you need explained? I'd be glad to help :)
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.
Cheers.
Answer:
B.
Step-by-step explanation:
The order of the letters in the side's name should correspond to their position in the name of the triangle.
Answer:
(-3 ,2.5)
Step-by-step explanation:
midpoint formula is
x1+x2 y1+y2
(___ , _____ )
2 2
(-7,-2) -7 is x1 i.e the first x point and -2 is y1 1st y point
(1,7) 1 is x2 i.e the second x point and 7 is y2 the second y point
now we use input the numbers to the formula
-7+1 -2+7
(____ , --------)
2 2
we the signs are different you subtract and use sign of greater number
-6 5
__ , ___
2 2
Now you divide
and here is the ordered pair for midpoint.
(-3 ,2.5)
where a=a, then b=c
