I need help with this and don't know the answer to this problem.

x = 122°

w = 90°

Step-by-step explanation:

x + 58° = 180°

[Sum of linear pair of angles measure 180°. If the pair is a set of two angles then the angles of this linear pair are called as Supplementary angles]

x = 180° - 58°

x = 122°

Similarly, w + 90° = 180°

w = 180° - 90°

w = 90°

Therefore, values of each variable are x = 122° and w = 90°.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
