Answer:

5. tan(25) = 12/x

x · tan(25) = 12

x = 12/tan(25)

= 25.734

≈ 25.73

6. tan(52) = x/3.4

x = 3.4tan(52)

= 4.352

≈ 4.4

Answer:

$AB=148.76\ m$

Step-by-step explanation:

<u><em>The complete question in the attached figure</em></u>

we know that

The triangle PAB is a right triangle because the sum of ∠APB and ∠PAB is equal to 90 degrees

In the right triangle PAB

$sin(\angle APB)=\frac{AB}{AP}$ ----> by SOH (opposite side divided by the hypotenuse)

substitute the given values

$sin(25^o)=\frac{AB}{352}$

solve for AB

$AB=sin(25^o)(352)=148.76\ m$

1. nth term=3n-1

20th term=3(20)-1=60-1=59

2. nth term=-2n-4

20th term=-2(20)-4=-40-4=-44

3. nth term= $\frac{2}{3}$ n- $\frac{2}{3}$

20th term= $\frac{2}{3}$ (20)- $\frac{2}{3}$ = $\frac{40}{3}$ - $\frac{2}{3}$ = $\frac{38}{3}$

4. nth term=- $\frac{1}{3}$ n+ $\frac{11}{15}$

20th term=- $\frac{1}{3}$ (20)+ $\frac{11}{15}$ =- $\frac{20}{3}$ + $\frac{11}{15}$ =- $\frac{89}{15}$
