Answer:

∠A = 45°

Step-by-step explanation:

◺ABC is a right angled triangle.

Sum of interior angles in a triangles is 180.

∠A + ∠B + ∠C = 180°

∠A + 90° + 45° = 180°

∠A = ( 180 - 90 - 45 )°

∠A = 45°

Note : -

□ is 90°

Answer:

Step-by-step explanation:

If you have something that says it is the f(x) or just f(something) then that is just telling you what the x equals. In this case, x=4 so you plug that into the equation.

This gives you f(4)=4(4)+7. From here, you will use the order of operations to solve.

f(4)=4*4+7

f(4)=16+7

f(4)=23
