Answer:
C) 55
Step-by-step explanation:
One of the angles is given, which is 35. This is a right triangle because there is a square next to angle C, meaning it is 90 degrees. You subtract both of these values from the degree of a triangle, 180, which will leave you with 55.
55
Given: 35 degrees and 90 degrees
The total degrees of a triangle is 180
180 - 35 - 90 = 55
4(2x-1) ,x=5
4(2(5)-1)
4(10-1)
4(9)
