Answer:
d. 40
Step-by-step explanation:
2x + x +( x + 20) have to all equal 180 degrees in a triangle.
2x + x + x + 20 = 180
2x + 2x + 20 = 180
4x + 20 = 180
4x = 180 - 20
x = (180-20) / 4
x = 160 / 4
x = 40
Find the cube root of 125. ∛125 = 5. Each side length will be 5 inches.
In point slope form, required equation is given by (y - y1) = m(x - x1); where m = (y2 - y1)/(x2 - x1) = (4 + 1)/(8 - 2) = 5/6
Required equation is y + 1 = 5/6 (x - 2)
In standard form, 6y + 6 = 5x - 10 => 5x - 6y = 6 + 10 => 5x - 6y = 16
Distribute
remember a(b+c)=ab+ac
8(y+4)=8(y)+8(4)=8y+32
8y+32=7y+38
minus 7y both sides
y+32=38
mius 32 oth sides
y=6
Answer:
O is largest, C is medium, and T is smallest
Step-by-step explanation:
You need to pay close attention to the side length. The higher the length, the smaller the angle.
