SinA=cos(90-A)
Notice here 52=90-38
so the answer is 0
Let the digit in the tens place be x
tens place = x (therefore the value is 10x)
ones place = x + 7
The number is 10x + x + 7
Add 26 to it
10x + x + 7 + 26 = 11x + 33
It is 5 times the sum of the digit
11x + 33 = 5(x + x + 7)
11x 33 = 10x + 35
x = 2
x+ 7 = 2 + 7 = 9
So the number is 29
You know y=mx+ b in slip intercept for which means the y intercept is positive but when it is y=mx-b that means the y intercept is negative
Y = (7/8)x + 6, as the gradient is around 1 and the intercept is close to 6
Ten to the power of five.
