HELP ME PLEASE!! I’ve been going at it but I just can’t.

How many different triangles can be constructed with the angle measurements of 134° 10° and 36° ?

Asif spent $745.10 on 13 new file cabinets for his office. small file cabinets cost $43.50 and large file cabinets cost $65.95. write and solve a system of equations to find the number of small cabinets and large cabinets he purchased. determine if each statement is true or false. 1. he purchased 5 small cabinets. true or false 2. he purchased 7 large cabinets. true or false 3. he spent $527.60 on large cabinets. true or false

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
