By Sine Rule,
x/sin30° = 8/sin90°
x/0.5 = 8/1
So x = 4.
Answer:
c for plato users;)
Step-by-step explanation:
Area of a parallelogram=base x heigth
Data:
base=(2x+3)
heigth=(ax+5)
area of this parallelogram=8x²+bx+15
Therefore:
8x²+bx+15=(2x+3)(ax+5)
8x²+bx+15=2ax²+10x+3ax+15
8x²+bx+15=2ax²+(10+3a)x+15
Then:
8x²=2ax²
a=(8x²)/(2x²)=4
bx=(10+3(4))x
bx=(10+12)x
b=22x/x=22
Answer: a=4 and b=22.
Answer:
w=6ft
Step-by-step explanation:
72 divided by 12 is 6
Using the formula
A=wl
Solving for w
w=A
l=72
12=6ft
