B = 26in, c = 40in
a^2 = 26^2 + 40^2
= 2276 (square root it)
a = 2root569 // 47.7in
If you plug in the second equation (x=5-3/2y) into the first, you get:
5(5-3/2y) - 4y = 7
Simplify:
25 - 15/2y - 4y = 7
-15/2 y - 8/2 y = 7-25
23/2 y = 18
y = 18 * 2/23 = 36/23
answer B!
Answer: a 68 c57 b55 I think
Step-by-step explanation:
A triangles angles add up too 180 so just subtract the sum and the two angles and you are done.
Answer:
288 units^3
Step-by-step explanation:
To find the volume of this prism, first find the area of the triangular end.
A = (1/2)(base)(height) comes out to A = (1/2)(6)(8), or A = 24 square units.
Next, multiply this area by the length of the prism: V = (24 units^2)(12 units) = 288 units^3
The volume is 288 units^3
