Step-by-step explanation:
Answer:
∠ 1 = 72°
Step-by-step explanation:
(4n - 2) and (2n + 17) are adjacent angles and sum to 180° , that is
4n - 2 + 2n + 17 = 180
6n + 15 = 180 ( subtract 15 from both sides )
6n = 165 ( divide both sides by 6 )
n = 27.5
Then
2n + 17 = 2(27.5) + 17 = 55 + 17 = 72
∠ 1 and 2n + 17 are vertical angles and congruent , so
∠ 1 = 72°
<span>Larger angle measures four degrees more than seven times the smaller angle. ... The measure of one of two complementary angles is 21 less than twice the measure of the other angle. ... One angle is 4 degree less than 3 times the other.</span><span>

The answer for the exercise shown in the figure attached is shown below:
1- side lengths.
2- a^2+b^2=c^2
3- is a rigth triangle
Therefore, in other words, you can know that a triangle is a rigth triangle (which means that it has an angle of 90 degrees) when the square of its longest side is equatl to the sum of the squares of the other sides.
