ΔABC is a right triangle. CD is the altitude of the hypotenuse AB. If m∠A=60 and CD=6, find the perimeter of ΔABC 1. AC
2. AB
3. BC
4. Perimeter of ΔABC

1)

2)

3) BC = 12

4) the perimeter is

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
