It is possible because you can have 2 acute angles in the triangle and on right angle making it a acute right triangle.
sin (x) = -1
arcsin (-1) = x
x = -90
and multiples of 360
x =-90, 270,....
x =-90 + 360n where n is an integer
or in radians
-pi/2 + 2*pi *n where n is an integer
Answer:
C.) 7 and A.) 5
Step-by-step explanation:
Constants are numbers with no variable, they have no change, they are "constant"
Coefficients are the opposite, they are the numbers that are with variables and go through some sort of change
Answer:
27 in²
Step-by-step explanation:
The area (A) is calculated as
A = πr² ( r is the radius ) , then
A = π × 3² = 3 × 9 = 27 in²
A) For object with mass m1,
F = m1 * 3
m1 = F/3
For object with mass m2,
F = m2 * 1
m2 = F
Ratio of m1/m2
(F/3) / F = 1/3
