I think it’s 4 but not sure
Answer:
14 yd
Step-by-step explanation:
The cross section is a triangle with a height of 19 and a base of x
Area of a triangle = bh/2
133 = 19x/2
266 = 19x
x = 14
Since the signs are different, you have to subtract. 2
The only "simplify" answer would be in a decimal other than that 2 is not divisible into 45. If you can't fine a whole number that multiplied with the numerator gives you the exact number of the denominator that means that you would have to use decimals or radicals.
Divide it all by 2rs and the end answer would be 3.
