Step-by-step explanation:
all angles of a triangle sum to 180
180 = 15x + 24x +21x
180=60x
solve for x
then substitute that for 24(x) to get the angle
Answer:9.51
Step-by-step explanation:You add them for the total
70º
It's a supplementary angle so 180º - 110º
It’s 3/2 you can look at the the point (0,1) and (2,4) you can use a method called rise over run you got up 3 over 2 units to get to the next point
sorry if this is wrong but i think the answer is 21
