Perímeter of rectangular area= 2(long + width)
Then:
Perimeter =2.(50 m+10 m)=2.(60 m)=120 m
Sol: 50 m x 10 m
Answer:
40.5 degrees
Step-by-step explanation:
A triangle's angles all add up to 180 degrees, so to solve this all you need to do is add the two numbers you have and subtract them from 180.
62.5+77+x=180
139.5+x=180
-139.5 -139.5
x=40.5
Answer:
according to me it makes sense
but im not sure tho
Answer:
x = pi / 2 or pi / 6 or 5 pi / 6
Step-by-step explanation:
2 cos x sin x –cos x = 0
cos x ( 2 sin x – 1) = 0
cos x = 0 or 2 sin x – 1 = 0
x = pi/2 or sinx = 1/2
x= pi /2 or x = pi/6 or pi-pi/6
x = pi / 2 or pi / 6 or 5 pi / 6
as for sinx = k
if x is a solution, pi-x is also a solution
