The answer is 75
First you subtract 180 and 165 to find that smallest angle inside the triangle(15). Then you add 15 and 90,the two angles you know, and do 180 - 105= 75.
The trick is that all angles inside a triangle equal 180 degrees. Hope this helps!
Answer:
A choice
Step-by-step explanation:
sec is defined as 1/cos.
cos is again defined as adjacent to hypotenuse.
We know that adjacent is x and hypotenuse is r.
Therefore:- cos is x/r
Now sec is 1/cos = 1/(x/r)
1 ÷ x/r is 1•r/x
Thus:-
sec is r/x
Answer:
Distance from the moon is 2.4 × 10⁵ miles
Step-by-step explanation:
Length of 1-inch paperclip =
miles
Number of paperclips used to reach the moon = 1.5 × 10¹⁰
Total distance from the moon = Number of paper clips used × Length of one clip
= (1.5 × 10¹⁰) × (1.6 × 10⁻5)
= (1.5 × 1.6) (10¹⁰× 10⁻⁵)
= 2.4 × 10⁽¹⁰⁻⁵⁾ miles
= 2.4 × 10⁵ miles
Distance from the moon is 2.4 × 10⁵ miles.
Answer:
1900 = k
Step-by-step explanation:
38=k/50
Multiply each side by 50
50 *38 = k/50 *50
1900 = k
Answer:
C. 200 minutes, $260
Step-by-step explanation:
The equations would look like this
Lynn = y = 1.10x + 40
Heather = y = 1.15x + 30
Now just plug in.
Lynn
260 = 1.10(200) + 40
260 = 220 + 40
260 = 260
Heather
260 = 1.15(200) + 30
260 = 230 + 30
260 = 260
Hope this helps ya! Keep smiling!
