Answer:
5. m < 1 = 72 degrees.
6. m < 1 = 80 degrees.
Step-by-step explanation:
5. < 1 = 72 degrees.
If we draw a line through the point of < 1, We see that We have have 2 angles of 40 and 32 ( alternate angles).
6. By the same reasoning m < 1 = 60 + 20
= 80 degrees.

Step-by-step explanation:
We need a picture of what you're talking about.
Answer:
Step-by-step explanation:
l -> length
b -> width
h -> height
Find the area of four walls and ceiling. then subtract the area of four windows and a door form that area.
Area of four walls + <u>ceiling</u> = 2( lh + bh) +<u>lb</u>
= 2*(20*5 + 15*5) + 20*15
= 2( 100 + 75) + 300
= 2* 175 + 300
= 350 +300
= 650 sq m
Area of window = 2 *3 = 6 sq.m
Area of four windows = 4*6 = 24 sq.m
Area of door = 2 * 1 = 2 sq.m
Area of four walls excluding 4 windows and door = 650 - 24 - 2 = 624 sq.m
Cost of painting = 624 * 6.50
= $ 4056
No, because negative base sometimes results in non-real or imaginary value.
