I just need question number 1, asap though, please! I need it by 12pm est

tanA=3/4

Step-by-step explanation: If  cosA=4/5 then

sinA=√(1−cos2A)  {Because sin^2A+cos^2A=1}

=>sinA=√(1−16/25)

=>sinA=√(9/25)

=>sinA=3/5

Now as  tanA=sinA/cosA

=>tanA=3/5×5/4  {Because 1/cosA=5/4}

=>tanA=3/4

5x+2x=49

7x=49

x=7. 35 apples

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
