Answer:
no
Step-by-step explanation:
Using the converse of Pythagoras' identity.
If the square of the longest side is equal to the sum of the squares of the other 2 sides then the triangle is right.
longest side = 30 , then 30² = 900
20² + 23² = 400 + 529 = 929 ≠ 900
Then the triangle is not right.

Answer:
F = -79.78
Step-by-step explanation:
You need to set F by itself
5/9(F-32) = -62.1
multiply the reciprocal of 5/9 on both sides to eliminate 5/9. The reciprocal is 9/5
-62.1 times 9/5
= -111.78
F-32 = -111.78
add 32 on both sides to get F by itself.
-111.78 + 32 = -79.78
Your final answer
Step-by-step explanation:
a1 = 27
r = -9/27 = -⅓
the formula :
an = a1. r^(n-1)
= 27. (-⅓)^(n-1)
= 3³(-3`¹)^(n-1)
= 3³(-3)^(1-n)
Area of a circle = pi x r^2
Area of circle = 150,000/ 1578 = 95.06 square miles
95.06 = 3.14 x r ^2
Divide both sides by 3.14
R^2 = 30.27
Find the square root:
R = sqrt(30.27)
R = 5.5
The radius is c) 5.5 miles
