If 3sinA+4cosA=5 then find the value of cosA

Cos A =1.4

Step-by-step explanation:

3sinA=5-4cosA; square both sides: 9sin^2(A)=25-40cosA+16cos^2(A);

9-9cos^2(A)=25-40cosA+16cos^2(A); 25cos^2(A)-40cosA+16=0=(5cosA-4)^2.

cosA=4/5 so sinA=3/5 (√(1-16/25) and sinA+cosA=7/5=1.4.

8 is in the ten-thousands place.

Step-by-step explanation:

Place value of a digit is the value represented by a digit in a number on the basis of its position in the number.

In the given number 325,785,901 the digit 8 is in the ten-thousands place.

You should count the number of digits from right to left, and you can see 8 is in the position "5" and its corresponds to the ten-thousands place.
