Answer:
10 cm
Step-by-step explanation:
we know that the perimeter of a rectangle= 2(l+w)
given that the perimeter is 46 cm and length is 13 cm, so by putting the values we get,
2(13+w)=46
= 26+2w=46 (opening the brackets)
= 2w= 46-26
= 2w=20
= w=20/2
w= 10 cm

Answer
Step-by-step explanation:
hope you have an good day aswell ;D
Recall that all three angles in a triangle equals 180.
Knowing this, we just have to add up all the angles and figure out what the value 'x' is.
(x-22 + x-17 + 3x+19) = 180
Simplify:
5x - 20 = 180
Add 20 to both sides:
5x = 200
Divide both sides by 5:
x = 40
Now that we found the value for x, we need to solve for angle A.
Simply input the value of 'x' into angle A's equation:
40 - 22 = 18
Angle A = 18 degrees
Good luck! If you need me to explain anything, just ask :))
