I believe $46 have been saved. You multiply 6x6 and get 36. Then you add 10 to the sum. So the answer is 46.
Answer:
-1/2
Step-by-step explanation:
y=mx+b is used to find the slope. The m part of the equation is the slope
A triangle with 45 cm of perimeter has 15 cm of side. The
"altitude" connects the middle of one side to the opposite vertice. This forms a rectangle triangle with hypothenuse 15 cm and the small catet a= 7.5 cm. So by the Pythagoras theorem we must solve the equation:
7.5^2+b^2=15^2
b=sqrt(225-56.25)=sqrt(168.75)=12.99 cm
Other solution was using trigonometry:
b/(side)= sin(pi/3)=sqrt(3)/2
b=7.5*sqrt(3)/2=12.99 cm
Answer:
19/5
Step-by-step explanation:
I take it you meant θ angle, anyway.
we know the tan(θ) = -4/7... alrite, we also know that 270° < θ < 360°, which is another to say that θ is in the IV quadrant, where the adjacent side or "x" value is positive whilst the opposite side or "y" value is negative.
