Answer:
Step-by-step explanation:
12²+16²=144+256=400=20²
so it is a right angled triangle.
let BC bebase and AB=height or perpendicular
AC=hypotenuse
sinC=12/20=3/5=0.6
cosC=16/20=4/5=0.8
tan C=12/16=3/4=0.75
similarly sin A=16/20=4/5=0.8
cos A=12/20=3/5=0.6
tan A=16/12=4/3≈1.33

☺ Hello mate__ ❤
◾◾here is your answer...
i think right question is this
(3x − 7y)^2
ok now start solving:-
(3x − 7y)^2
=> (3x − 7y) (3x − 7y)
=> 3x(3x- 7y) -7y(3x-7y)
=>. 3x.3x - 3x.7y-7y. 3x + 7y.7y
=> 9x^2 -27xy +27xy + 49y^2
=> 9x^2 + 49y^2
so your correct ans. is 9x2 + 49y2

I hope, this will help you.☺
Thank you______❤

Answer: 70%</h3>
Reason:
Subtract the given probability from 100% to get the chance that it doesn't rain. So 100% - 30% = 70%
This is because we have two outcomes: it rains or it doesn't rain.
The probability of each outcome must add to 100%.
Answer:
Step-by-step explanation:
Arrange the equations so that all the variables are in columns (x as the first column, y as the second, equals a number as the third):
-11x - 4y = 36
5x + 5y = -10
Define and edit Matrix A. We need a 3 x 2 matrix. Input the coefficients and constant:
![\left[\begin{array}{ccc}-11&-4&36\\5&5&-10\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-11%26-4%2636%5C%5C5%265%26-10%5Cend%7Barray%7D%5Cright%5D)
Find rref function, enter matrix A: rref([A]) (press enter)
This gives you:
![\left[\begin{array}{ccc}1&0&-\frac{44}{7}\\0&1&\frac{58}{7}\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%260%26-%5Cfrac%7B44%7D%7B7%7D%5C%5C0%261%26%5Cfrac%7B58%7D%7B7%7D%5Cend%7Barray%7D%5Cright%5D)
which means:
