Please help I don’t understand

Line m and n are parallel lines that are intersected by a line

This means that corresponding angles in each line are equal to each other

This means that angle (3x+58) is equal to (5x)

now, we can solve for x and from there find the angle measure

(3x+58)=5x

3x-3x+58=5x-3x

58=2x

58/2=2x/2

29=x

if 29=x then 5(29)=5x

the angle measure of these angles is 145

Step-by-step explanation:

Step-by-step explanation:

m // n  and they are intersected by transversal.

Corresponding angles are equal

5x = 3x + 58

5x - 3x = 58

     2x = 58

      x = 58/2

x = 29

5/6

step-by-step explanation:

if i remember correctly with perpendicular stuff you just take away the negative

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
