Answer:
x=56 and the exterior angle is 116
Step-by-step explanation:
We will call the unknown angle in the triangle y. Angle y and the angle (2x +4) form a straight line so they make 180 degrees.
y + 2x+4 =180
Solve for y by subtracting 2x+4 from each side.
y + 2x+4 - (2x+4) =180 - (2x+4)
y = 180-2x-4
y = 176-2x
The three angles of a triangle add to 180 degrees
x+ y+ 60 = 180
x+ (176-2x)+60 = 180
Combine like terms
-x +236=180
Subtract 236 from each side
-x+236-236 = 180-236
-x = -56
Multiply each side by -1
-1*-x = -56*-1
x=56
The exterior angle is 2x+4. Substitute x=56 into the equation.
2(56)+4
112+4
116
Answer:
Step-by-step explanation:
you take 5280( How many feet are in a mile) and dived it by 3. The equals 1760 and that is the answer because 1760 is 1/3 of 5280
Answer:1760
Answer: n=4
Step-by-step explanation: 1:4 = 6:24

answer
17,000,000
Just plug it in:
c & d = c² + d² - 4
2 & 1 = 1² + 2² - 4
= 1 + 4 - 4 = 1
