Answer:
18
Step-by-step explanation:
4x + 5x = 180
10x = 180
x = 18
2.57*10^4 is 1,000,000 times more than 2.57*10^-1
Why?
4-(-1)=5 2
2.57*10^4=25700
2.57*10^-1=0.0257
and
25700
÷ 0.0257
=1000000
and 1000000=10^6
Number name is the same as word form
8.542 = eight and five hundred fourty-two thousandths.

Answer:
C. m∠N = 69°
Step-by-step explanation:
The sum of the measures of the angles of a triangle is 180.
m∠L + m∠M + m∠N = 180
36 + 75 + m∠N = 180
111 + m∠N = 180
m∠N = 69°
