Answer:
29
Step-by-step explanation:
Since all triangles have to add up to 180, we can do the sum of the two angles we know minus 180. 90+61=151, 180-151=29
So your answer would be 29
The answer is up three and up four
No not all since for example 5.0 is in decimal form but is not a rational number
4+2.2h=-3.7
2.2h=-7.7
h=-7.7/2.2=-7/2=-3.5
The answer is -3.5
Good luck!
