Answer:
a is the right answer atleast that's what I think
Answer:
The answer would be 50% or 1/2
Step-by-step explanation:
.3 (100) = moving the decimal to the right 2 times because of the two zero's in '100'
So .3 (100)= 30
When 1 is added to another 1 they join together to form a 2. Bruh idk what 1+1 long method is. But I hope it helped.
Area of a triangle:
A= (1/2)(bh)
In this problem we are given:
A= 178.5

b= h+4 in
h= UNKNOWN ("h")
Plug in our values into the area equation and solve for "h":


(multiply each side by 2 to get rid of the 1/2)



(357/21=17)

(solve both inequalities separately)


( a negative height is not possible so, this answer is incorrect.)


Answer: base = (h+4)= (17+ 4)
b= 21 in h= 17inPlease comment with any further questions! :)
