Pls help asap :_: Steven knows that the first angle of a triangle measures 98 degrees, and the second angle measures 37 degrees.

Which equation could Steven use to find x, the measure of the third angle?
a)x = 180 + 98 + 37

b)x = (98 + 37) ÷ 180

c)x = 180 − (98 + 37)

d)x = 3 × (98 + 37)

c

Step-by-step explanation:

angles in a triangle add to 180

so you do 98 + 37

then take that away from 180

so

x = 180 − (98 + 37)
