Did you already find the answer?
Answer:
45 square units.
Step-by-step explanation:
Applying the pythagoras theorem:
Base of the bigger triangle =
=
= 12 units
Area of a triangle is given by
× base × height
The area of the bigger triangle is
× 12 × 9 = 54 square units.
The area of the smallest triangle is
× (12 - 10) × 9 = 9 square units.
The area of the figure( required triangle) is 54 - 9 = 45 square units.
The B option is the correct answer
Oh, I remember this one. Here's this if you need it, if it doesn't help then let me know.
I believe the answer would be 50
explanation:
calculate
2 ÷ 5^-2
use negative power rule x^-a = 1/x^a
2 ÷ 1/5^2
simply 5^2 to 25
2 ÷ 1/25
use this rule a ÷ b/c = a • c/b
2 • 25
simplify
50
