Find the missing dimension of a triangle:
height: 15 ft
area: 285 ft squared
A = 1/2 * b * h
285 = 1/2 * 15b
285 = 7.5b
285/7.5 = b
38 = b
A=bh÷2
A=??×15=÷2
A=??÷2
A=285
B=19
this is dumb i did not get the anwser i was looking for i needed to find the missing number of a triangle with the area 18.7 and the base is 17
38
The answer is 19! >w<
I change it it is 38
570÷15=38
Idk the answer but there’s this guy that I really like and he shows signs that he likes me too but he post hella girls on his story and so I’m confused ✨ ok byee
The answer is 38 I checked it several times it is 38
To find the missing dimension of a triangle, we can use the formula for the area of a triangle:
Area = 1/2 * base * height
In this case, you are given the height (15 ft) and the area (285 ft²). We can substitute these values into the formula and solve for the missing dimension, which is the base.
285 ft² = 1/2 * base * 15 ft
To isolate the base, we need to get rid of the fraction by multiplying both sides of the equation by 2:
2 * 285 ft² = 2 * (1/2 * base * 15 ft)
570 ft² = base * 15 ft
Now, divide both sides of the equation by 15 ft to solve for the base:
570 ft² / 15 ft = base
The unit of ft² will cancel out with ft, leaving us with the base in feet:
base = 38 ft
Therefore, the missing dimension, the base of the triangle, is 38 feet.
