Answer:
volume of rectangular prism =l×w×h
volume of rectangular prism =4cm×2cm×7cm
volume of rectangular prism =56cm³
Answer:
y=10°
Step-by-step explanation:
Here,
→(3x+18)°=(5x-4)°
→18°+4°=5x-3x
→22°=2x
→x=11°
Also,
3(4y+3)°+5x-4°=180°[The sum of the linear pair is 180°]
12y+9°+5x-4°=180°
12y+5°+5×11°=180°
12y+5°+55°=180°
12y=180°-60°
12y=120°
y=120°/12
y=10°
Answer: 117 degrees
Step-by-step explanation:
Answer:
Step-by-step explanation:
First, find the slope of the line:
The formula for finding the slope is:
Plug in the points:
= =
So now the equation is y = x + b
Now solve for b by plugging in one of the points:
(2,7)
y = x + b
7 = 2 + b
7 = + b
b =
So the equation will be
You can add them up using a calculator, the answer is 77.32
