It would be written as
T < 5, but there would be a line underneath the less then sign
First one is 12^2
second one is 1
Answer:
A, C, E
Step-by-step explanation:
Only letters T, A, and X on the triangle can be used to describe it, regardless of the order they are in.
Add 2.2 to each side so 0.3z = 5.2 - 0.5z -0.8z
add 0.5z to each side so 0.8z = 5.2 - 0.8z
add 0.8z to each side so 1.4z = 5.2
divide each side by 1.4 so z = 3.71428571
Answer:
A ≈ 35.3 units²
Step-by-step explanation:
Calculate the radius CB using Pythagoras' identity in the right triangle.
CB² + AB² = AC²
CB² + 6² = 9²
CB² + 36 = 81 ( subtract 36 from both sides )
CB² = 45 = r²
Then area of quarter circle is
A = × πr² = × π × 45 ≈ 35.3
