Answer:
x = 13.
So the 3 angles are a = 44, b = 47 and c = 89 degrees.
Step-by-step explanation:
If these are the angles are the 3 angles of a triangle they sum to 180 degrees, so:
3x + 5 + 5x - 18 + 7x - 2 = 180
15x - 15 = 180
15x = 195
x = 195/15
x = 13.
Answer:
Interest Rate : 0.0346 or 3.46%
Step-by-step explanation:
• 429.2=350*(1+x)^6
• 429.2/350= (1+x)^6
•(429.2/350)^(1/6)= 1+x
•(429.2/350)^(1/6)-1= x
Check work:
350*(1+0.0346)^6=429.2
