Answer:
D
Step-by-step explanation:
20% of 80= 16
20% of 70= 14
16+16+14+14+14=74
Answer:
4 ft , 16 ft & 20 ft
Step-by-step explanation:
40 = x + 4x + 5x = 10x --> x = 4
7x-35<2x-10 distribut it
7x-2x<-10+35 collect like them
5x<25 divide both side by 5
x<5
Answer: fifty four degrees (54)
Step-by-step explanation: Using the law of sines you'd multiply both sides by b then plug in the known values... sin(B)= 9/11xsin(80degrees). Then, you'd evaluate to find B and after solving you'd reach 54
