Why don't you first try to use the cosine law to solve for an angle and then make use of the sin law to solve for the remaining angles.
Cosine law
C^2 = A^2 + B^2 - 2AB(cos C)
Solve for cos C, and then take the inverse of the trig ratio to solve for the angle.
Then set up a proportion like you have done using the sin law and solve for another angle. Knowing the sum of all angles in a triangle add up to 180 degrees, we can easily solve for the remaining angle.
I'm her first quiz she did better, this is going to be hard to explain but pay attention 92% as a decimal is 92/100 keep this in mind, then 27 out of 30 question we try to make 30 go into 100 but we know 30 can't go into 100 without a decimal so what we do is we change the decimal to 90 so for the 27 out of 30 it is now 81/90, now we need to change the denominator in 92/100 to 90 so we subtract 10 from the numerator and denominator to get 82/100 so compare the 2 decimals you got 81/90 and 82/90 and you find that 82/90 is bigger so she did better on the first quiz
Perimeter is the sum of all the sides of the shape
do you know the length of each side of the parallelogram?
1/3 is greater than 1/5 and 1/4.
Answer:
see explanation
Step-by-step explanation:
Given D(3, 2 ) → D'(2, 4 )
The x- coordinate of D' is 1 less than D and the y- coordinate of D' is 2 more than D, thus the translation rule is
(x, y ) → (x - 1, y + 2 )
Apply this rule to points O and G
O( 2, - 4 ) → O'(2 - 1, - 4 + 2 ) → O'(1, - 2 )
G(- 1, - 1 ) → G'(- 1 - 1, - 1 + 2 ) → G'(- 2, 1 )
