Answer:
Step-by-step explanation:
The opposing side and the hypotenuse for the angle are given.
Remember, when the opposing side and the hypotenuse are given, take the cos ratio.
- cosx = 7/9
- x = cos⁻¹ (7/9)
- x = 38.9424413°
- <u>x = 39°</u>
Answer:
The correct answer is: -7, 7
Step-by-step explanation:
Given numbers are:
-7, 0, 7, 14
We have to check all pairs of numbers with respect to sum to check that which pair of numbers sums up to zero. So first of all, we will take -7 and will find its sum with other numbers.
So,

We can see that the sum of -7 and 7 is zero.
Hence,
The correct answer is: -7, 7
Answer:
55.96 miles
Step-by-step explanation:
Distance = Speed X time
Car first moved east for 1 hr , distance = 40 x 1 = 40 miles
Car then moved north-east for 30 min, distance = 40 x 0.5 = 20 miles
From trigonometry,
sin 45 =
; y = 20 sin 45 ; y= 14.14 miles
cos 45 =
; x = 20 cos 45 ; x = 14.14 miles
using Pythagoras theorem;
=
+ 
=
+ 
= 3131.08
= 
z = 55.96 miles

Answer:
6
Step-by-step explanation:
Integers are whole numbers that do not have decimals.
4.18 ÷ 0.68 = 6.14
Remember, round down with 0-4, round up with 5-9.
6.14 can be rounded down to 6.
