Answer:
The sum of the interior angles of any triangle are equal to 180
therefore in this triangle, m<a+m<c+m<b=180
we know that 9x-26 and m<a are supplementary angles (meaning they add to 180) and therefore,
9x-26+a=180
9x+a=206
a=206-9x
(206-9x)+(2x-12)+(4x+43)=180
combine like terms
-3x+237=180
-3x=-57
x=19
if x=19 then we can substitue it in for c
4x+43=c
4(19)+43=c
c=119

Answer:
Speed of car in miles per minute = 0.8 miles per minute
Distance cover by car in 20 minutes = 16 miles
Step-by-step explanation:
Given:
Speed of car = 48 miles per hour
Time taken by car = 20 minutes
Find:
Speed of car in miles per minute
Distance cover by car in 20 minutes
Computation:
Speed of car = 48 miles per hour
1 hour = 60 minutes
So,
Speed of car = 48/60 miles per minute
Speed of car in miles per minute = 0.8 miles per minute
Distance cover by car in 20 minutes = 20 x Speed of car in miles per minute
Distance cover by car in 20 minutes = 20 x 0.8
Distance cover by car in 20 minutes = 16 miles
