Answer:
<h2>1. 36 2. height=5 base=11 area= 55</h2>
Step-by-step explanation:
To solve this, what you will need to do is find the solution of one variable and then substitute it and solve for the other.
Here’s how to solve:
y+2x=4
-2x -2x
y=4-2x
4-2x + 2x =4
4=4
So if you’re trying to see if it is true, then your answer is that it’s true.
If you’re trying to find the linear equation, then your answer is y=-2x+4.
Answer:
C. s= 75
Step-by-step explanation:
One radian is the angle subtended by an arc length equal to the radius of the circle.
∅=s/r where s is the arc length ∅ the angle and r the radius of the circle.
Thus s=∅×r
In the circle provided arc s subtends and angle of 5 radians.
s= 5 radians× 15
=75
The answer is C, as it is rounded to 2 decimal places / 3 significant figures, which is more than the others.
