The answer would be 4.301
Alright so what you are doing is getting the area of the whole triangle, and that formula is what you do so bxh is 5x12 and 5x12=60 then you need to divide 60 by 2 which is 30 so your answer will be
B 30m^2
Hi,
The answer would be D. Here's why.
You could just do trial and error or like an equation but to make it simple, use trial and error since it is only small number.
If x was 5 and y was -4, just replace them into the equations...
4x+y=16. if x=5 and y=-4, then the equation would be 4*5 +(-4)=16 then it would be 20-4=16. 16=16. There first equation solved. Now lets do the next one. 2x+3y=-2. If x=5 and y=-4, then the equation would 2*5+3*(-4)=-2. Simplify and you get 10+(-12)= -2. 10-12=-2. -2=-2
This is why the answer is D (5, -4)
Hope this helps!
The formula to find the area of a triangle is:
A = 1/2bh
84.335 = 1/2 b(8.35)
168.67 = 8.35b
20.2 = b.
84.335 = 1/2 (8.35)(20.2)
84.335 = 1/2(168.67)
84.335 = 84.335
The base is 20.2 in.
Hope this helps =)
opposite angles are equal
so <B = <D = 145
Answer
B. 145
