Answer:
∠B =
Step-by-step explanation:
Given : a=7 b=10 and C is a right triangle
solution :
refer the attached figure .
Since ΔACB is right angled triangle so we will use trigonometric ratios .

Perpendicular = b =10
Base=a=7
Putting value in formula:




Thus ∠B =
Answer:
x= 7 y= 9 (7,9)
Step-by-step explanation:
solve by using system if equations. multiply top answer by 2, giving u 2y=2x+4 and y=2x-5 subtract the equations. y=9 (the x cancels out) then put 9 in for y. 9=x+2. subtract 2. giving u 7. and now x =7
