The rise would have to be 12.
This is because in order to be "Similar" triangles the sides need to be proportionate.
(1/3 = 4/12)
Answer: 180= 38+(17x+1)+(3x+1), All the angles in a triangle add up to 180 degrees, so I made all the add measures equal to 180 degrees.
Just solve that equation to find x. Then used then plug in the x value to (17x+1). After you solve that put it equal to 2y to solve for y.
So the y equation would look like: 2y=(17x+1) (but you would have solved for x and then plugged it in to the equation)
If you need help solving or have any questions let me know!
Answer:
Step-by-step explanation:
I'm guessing you want the volume?
so for a triangle it's 1/2 base * height for the area
1/2 * 8 * 3 = 12
12*20=240 m^3
Answer: x=8
Step-by-step explanation:
Since we are given that ∠ABC and ∠DBC are complementary angles, we know that adding them together should give us 90°. We can use this to solve for x.
6x+13+4x-3=90 [combine like terms]
10x+10=90 [subtract both sides by 10]
10x=80 [divide both sides by 10]
x=8
Now, we know that x=8.
