Answer:
y=70
x=55
Step-by-step explanation:
In an equilateral triangle, all the angles measure 60 degrees. Knowing this, we can set the following equations:
Add 10 to both sides
Subtract both sides by 5
I hope this helps!
Answer:
STEP 1: Find the circumference:
Circumference = 2πr
Circumference = 2π(14) = 28π cm
............................................................................................
STEP 2: Find the length of the arc:
Length of the arc = 36/360 x 28π
Length of the arc = 8.8 cm
.............................................................................................
Answer: The length of the arc is 8.8 cm

Lets call x how wide it is, and write the area equation:
area = width*length
a = (x)(x + 5) = 20000
expand it:
x^2 + 5x = 20000
make a quadratic trinomial:
x^2 + <span>5x - 20000 = 0
</span>lets apply the general quadratic formula to solve:
x = (-5 +- √(25 + 80000))/2
x = (-5 +- 282.89<span>)/2
we take the positive solution:
</span>x = (-5 + 282.89<span>)/2
</span>x = 138.94
therefore the rectangle width is 138.94 m and <span>143.94 m long</span>
Answer:
To move from (a, b) to (a, -b) move down 2b. The point (a, -b) would be in quadrant 4 and would be a reflection across the x-axis of the point (a, b)
