12 to 16 should be the only one.
i looked over ti and 9/12 is also equivalent.
if you multiple by 1.5 that gets you 9/12
Answer:
x = 13
39° and 51°
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
This is a right angle triangle, so one side has a size of 90 degrees.
3x + 4x - 1 + 90 = 180
7x + 89 = 180
7x = 91
x = 91/7
x = 13
Put x as 13 to work out the size of the angles.
3(13) = 39
4(13) - 1
52 - 1 = 51
Answer:
I think 20 is the answer of the question
Answer:
The answer is 138 degrees.
Step-by-step explanation:
Add both the opposite sides and, according to the Exterior Angle Theorem, the sum of those to sides will equal the exterior angle.
15.50 i think i not exactly sure but its around there
