Hello!
We have two expressions below.
7(6+2)
2(7)+6(7)
The area is 56 units squared.
I hope this helps!
Multiply the number by 100, making this one 115%
We know that
In any quadrilateral where the vertices are on the circumference of a circle, the opposite angles add up to
degrees.
So,
in this problem
therefore
the answer is
AB = 30 in and BC = 50 in.
We use Pythagorean theorem to solve this. Since AN is an altitude, this means that it is perpendicular to BC. This means BN and AN are the legs of one right triangle, with AB being the hypotenuse:
18²+24² = AB²
324 + 576 = AB²
900 = AB²
Take the square root of both sides:
√900 = √AB²
30 = AB
NC and AN form the legs of the other right triangle, with AC being the hypotenuse:
24²+NC² = 40²
576 + NC² = 1600
Subtract 576 from both sides:
576 + NC² - 576 = 1600 - 576
NC² = 1024
Take the square root of both sides:
√NC² = √1024
NC = 32
BC = BN + NC = 18 + 32 = 50
Answer:
arc length = 84.82 cm
Step-by-step explanation:
arc length = 36 * 3π/4
arc length = 3π * 9
arc length = 84.82 cm
Hope this helps!
