Solve 23t - 31 =24t - 30 for t. Round to the nearest tenth.

t= -1

Step-by-step explanation:

add 31 to both sides then you have 23t = 24t + 1

now subtract 24t from both sides and you have -t = 1

last, divide both sides by -1 to isolate the variable and then you have t = -1 for the answer

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
