Answer:
Step-by-step explanation:
I think across from each other is more direct. You could say two angles that are on opposite ends of a diagonal. That is probably clearest of all, now that I think of it.
Answer:
13
Step-by-step explanation:
12x2=24
50-24=26
26/2
13
double check
13x2=26
12x2=24
26+24=50
Hope this helps, love.
Step-by-step explanation:
let the angles be ' 7x, 8x and 5x'
as we know, the sum of all the angles of a triangle is 180 degree, so,
7x + 8x + 5x = 180
20 = 180
x = 180/2
x = 90 degrees
7x = 7 × 90 = 630 degree
8x = 8 × 90 = 720 degrees
5x = 5 × 90 = 540 degrees
therefore, 5x is the smallest degrees
A for the first one and D for the second
The answer to this is X = 9.
