Answer:
a = 9 meters
Step-by-step explanation:
The perimeter is the sum of the side lengths:
28 m = a + 2m + a + 8m
18 m = 2a . . . . . . . . . . . . . . . . subtract 10m, collect terms
9 m = a . . . . . . . . . . . . . . . divide by 2
The value of a is 9 meters.
Answer:
Step-by-step explanation:
Sum of the angles of a triangle is ALWAYS 180°.
2x+3x+5x = 180°
10x = 180°
x = 18°
2x = 36°
3x = 54°
5x = 90°
The angles are 36°, 54°, and 90°
Answer: b
Step-by-step explanation:
10 x 10= 100
15 x 10= 150
100+150= 250
15+m=34
-15. -15
M=19 N-12=-20 +12. +12
N=-8 V+16=8 -16. -16
V=-8 A-15=-5 +15. +15
A=10
