Please have a look at the photo attached in this answer
The missing part of the angle is 32 degrees, so the total angle of B is:
32 + 73 = 105 degrees.
Let x is the distance from airport A to airport C to the nearest tenth of a mile, we use cosine law to find x:
= - 2(570)(390)cos(105)
<=> = 592070
<=> x = = 769.46 miles
Answer:right
Step-by-step explanation:
Answer:
Step-by-step explanation:
We are given the expression:
We want to find the value of the expression when y=8 and z=9. Therefore, we must substitute 8 in for y and 9 in for z.
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Multiply 5 and 8.
Multiply 2 and 9.
Subtract 18 from 40.
The value of the expression 5y-2z at y=8 and z=9 is 22.
