Answer:
21
Step-by-step explanation:
Add all the numbers together
6+8+2.5+2.5+2=21
Answer: (2*5.4*7)+(2*5*8)+(7*8)
Step-by-step explanation:
You can add, subtract, and multiply them. These three operations obey the rules for integers. There's a polynomial division algorithm that fills formally the same role as the usual division algorithm for integers. Polynomials added to, subtracted from, or multiplied by other polynomials yield only polynomials. Likewise, integers added to, subtracted from, or multiplied by other integers yield only integers.
Answer:
30 degrees
Step-by-step explanation:
Since we know that all triangles equal 180 degrees, we can add the 2 given angles and subtract that from 180 to find the remaining angle.
90+60=150
180-150=30 degrees
