Angle A and angle B sums up to 180 (interior angles)
6x - 35 + 3x + 53 = 180
9x + 18 = 180
9x = 162
x = 18
angle A = 6(18)-35 = 73 degrees
7 mm wide
To solve this, you can use the Pythagorean theorem.
A triangle's sides is length squared + length squared = hypotenuse squared. We know the hypotenuse and one side of the triangle. So, we can follow the equation 24 squared + x squared = 25 squared
To solve this, find the value of 24 squared and 25 squared. 24 squared = 576, and 25 squared = 625, so your equation becomes 576 + x squared = 625
Next, you subtract your known values. 576 + x squared – 576 = 625 – 576 = 49, so x squared = 49
For the last step, find the square root (√) of 49, which is 7. So x = 7 mm
And you can check: 24 squared + 7 squared = 25 squared
