Answer:
Step-by-step explanation:
F=ma
28=7m
m=28/7=4
F=4a
when a=3 m/s²
F=4×3=12 N
Answer:
135°
Step-by-step explanation:
this is a cyclic quadrilateral, so the sum of opposite sides are 180
hence,
3x+6 + x+2 = 180
4x = 180 - (6+2)
4x = 172
x = 172/4
x = 43
therefore, m∠A is :
3(43) + 6
= 129 + 6
= 135°

Answer:
18
Step-by-step explanation:
4x + 5x = 180
10x = 180
x = 18
