The difference (-) is 18.
Answer:
Angle M = 98 degrees
Step-by-step explanation:
All triangle angles add up to 180.
Set up equation like this:
(x+6)+(3x-16)+(x)=180
Combine like terms.
5x-10=180
Add on both sides.
5x=190
Divide 5 both sides.
x=38
Solve for angle M.
3(38)-16=98
Answer:
C) 549 km²
Step-by-step explanation:
The area of the regular pentagon is given by ...
A = (1/2)Pa
where P represents the perimeter, and 'a' represents the apothem (6.2 km). Of course, the perimeter is 5 times the side length.
The lateral area is the product of the perimeter and the height:
LA = Ph
Using these formulas, and recognizing the total area includes two (2) pentagons, we have ...
total area = (LA) +2(A) = Ph +2(1/2)Pa = P(h +a)
= (45 km)(6 km +6.2 km) = 549 km^2
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The angles 2 and 3 are corresponding angles. So it's choice C.
<em><u>Tip:</u></em> Any pair of angles each of which is on the same side of one of two lines cut by a transversal and on the same side of the transversal.
