Question

Please answer this question please request to you Only 23 and 25 number please ​

Answer 1

Step-by-step explanation:

23 radius and tangent form 90 degree angle

po^2=pt^2+to^2

(4+r)^2=8^2+r^2

16+r^2+8r=64+r^2

8r=48

r=6cm

25 tan(A+B=root3=tan60

A+B=60

tan(A-B)=1/root3=tan30

A-B=30

by solving equations

A=45 and b=15

or

sinacosb+cosasinb=sin(a+b)=sin(60+30)=sin90=1
