Things to remember the sum of the measures of the interior and exterior angles at each vertex is 180 (supplementary angles)
add and equal to 180
3x-5+5x+17= 180
8x+12=180
8x= 168
x=21
substitute in the algebraic expression for exterior angle
3(21) -5=
63-5=58
58 degrees is the exterior angle
hope this helps
Answer:
106
Explanation:
3a+b2
Substitute the values for the variables:
3(14) + 2(32)
Solve:
3(14) + 2(32)
42 + 64
106
Answer:
y=-x+3
Step-by-step explanation:
rise/run
-1/1
-1
FIrst we know that
1 second = 1/3600 hours
5280 ft = 1 miles
Which means that
50 Ft = 50/5280 miles
So the conversion
(5/5280 miles ) / (1/3600)
= 5/5280 miles x 3600
= 34.09 miles per hour
