What is the value of h? h = 20 h = 35 h = 55 h = 70

h = 55

Step-by-step explanation:

Each of the angles adjacent to 2h° on the straight line = (180° - 2h°)

We also know that all internal angles of a triangle add up to 180

Hence,

40 + (180-2h) + (180-2h) = 180

40 + 180 -2h + 180 - 2h = 180

220 -4h = 0

4h = 220

h = 55

answer for #1 is c
