I believe the correct answer from the choices listed above is the last option. The measure of an exterior angle at the vertex of a polygon never equals the measure of the adjacent interior angle. Rather, they are always supplementary angles.
Hope this answers the question. Have a nice day.
Answer:
12
Step-by-step explanation:
4 times 1 is 4 time .25 is 1 times 2 is 2 times the heigh is 12
Answer:
11/9
Step-by-step explanation:
To find the slope
m = ( y2-y1)/(x2-x1)
= ( 9 - -2)/(1 - -8)
= ( 9+2)/ (1+8)
= 11/9
5s + 5l = 155, 10s + 12l = 346
Solve for s in the first equation.
5s = 155 - 5l
s = 31 - l
Substitute s into the second equation.
10(31 - l) + 12l = 346
310 - 10l + 12l = 346
310 + 2l = 346
2l = 36
l = 18
Substitute l into the first equation.
5s + 5(18) = 155
5s + 90 = 155
5s = 65
s = 13
s = 13, l = 18
