Answer:
Step-by-step explanation:
Area of triangular prism =base area * height
= 12 * 11
= 132 sq. cm
X + y = 1.....x = 1 - y
x * y = 0.09
y(1 - y) = 0.09
y - y^2 = 0.09....re-arrange
y^2 - y + 0.09 = 0
(y - 0.9)(y - 0.1) = 0
y - 0.9 = 0 x + y = 1
y = 0.9 x + 0.9 = 1
x = 0.1
y - 0.1 x + y = 1
y = 0.1 x + 0.1 = 1
x = 0.9
so ur 2 numbers are : 0.1 and 0.9
The answer would be 8000.
Answer:
Sin(460 radians)= .97054
sin(460 degrees)= 0.98480775301
Step-by-step explanation:
I'm not sure where you are from, but usually you are allowed to use a calculator. (At least I was when I took Algebra 2/Trig in 6th grade.)
You never specified radians or degrees so I will answer both.
sin(460 radians)= .97054
sin(460 degrees)= 0.98480775301
If you are not allowed to use a calc, then I suggest looking at unit circle videos on Khan Academy.
1. D. The triangles have two given sides with an included angle, so the postulate would be SAS.
2. A. The triangles have three given sides, so the postulate would be SSS.
