So the exterior angle of any polygons are 360 in total. since in the pic there r some interior angles, we need to 180 - interior to get the exterior angle. since they're adjacent angles on a straight line.
so therefore we get
51 + 66 + x + 180 - 132 + 78 + 180 - 139 = 360 (sum of exterior angle of polygon)
284 + x = 360
x = 76°
so it's C.
Answer: y=0.074x+50.48
Step-by-step explanation:
More squares than triangles
Answer: equilateral y=60
Step-by-step explanation:
The sum of all the angles in a triangle add up to 180 degrees. So, because you have the angle measurement of two sides, you can set up an equation to solve for the third side: 60+60+x=180 (do the math and you end up with y=60)
And because all three of the angle measures are equal, the triangle is defined as an equilateral triangle.
Answer:
$25.60
Step-by-step explanation:
0.25 miles = $0.80
Multiply by 4 on both sides to get $/mile
0.25(4) = $0.80(4)
1 mile = $3.20
Multiply by 8 (miles)
1(8) = $3.20(8)
8 miles = 25.6
If Emily bikes 8 miles, her mother will donate $25.60
Hope this helps :)
