are you looking for the h?
h=75
Answer:
Step-by-step explanation:
Value of 500 increased by 12% is 560
Area of triangle = 1/2 x base x height
so old triangle we have 1/2 x b x h = 48
new triangle has base 3 times as long and height is half as long
so we would get:
1/2 x (3B) x (1/2H) = area
rewrite as 1/2 x 3/2 x b x H = area
divide by original are os 1/2 x b x h and you end up with 3/2
so new area = 3/2 x old area
new area = 3/2 * 48 = 72 square inches
ANSWER
56.1 square inches.
EXPLANATION
The area of this triangle can be calculated using the formula,

where a=8in.
b=14.2 in.
and C=99° is the included angle.
We plug in these values to obtain,


We round to the nearest tenth to get,
56.1 sq. inch
