Answer:
42 square centimeters
I think that is the right answer
sorry if it is wrong
B)
Because if you find the degrees for angle 1 you get:
180⁰ - 45⁰- 39⁰ = 96⁰ <- angle 1
The triangle in the center has 3 angles, and those 3 angles will equal 180⁰
So, 180⁰ - 96⁰ = 84⁰
Refer to the other answer to see how letter c was done
It's an expression that can be simplified to read
( 0.7 x 0.4 ) ( b³ x b⁹ )
= ( 0.28 ) ( b¹² ) = 0.28 b¹² .
Answer:
Step-by-step explanation:
You can use SOH or CAH to find one of the sides
and then just a²+b²=c² to find the last one
