Answer:
4
Step-by-step explanation:
Because if you have 2 apples and add 2 apples to that, you'll have a total of 4.
Answer:
C
Step-by-step explanation:
The sum of the angles on a triangle must always equal 180 degrees. That means...
40 + 60 + (2n - 10) = 180
100 - 10 + 2n = 180
90 + 2n = 180
90 - 90 + 2n = 180 - 90
2n = 90
n = 45
I hope this helps!
Answer:
9
Step-by-step explanation:
let's assume ;
12=a
15=c
?=b
so;
a2+b2=c2
(12)2+b2=(15)2
144+b2=225
b2=225-144
b2=81 (square root both sides)
You'll get
b=9
NB; 2 is used as squared
Answer:
Step-by-step explanation:
We use trig to answer these questions:
sin x = opposite side of a triangle / hypotenuse
cos x = adjacent side / hypotenuse
Construct a right triangle with hypotenuse 4 m and lower angle 68 degrees.
The height of the top of the ladder is then defined by:
sin 68 degrees = height / 4 m, which yields (4 m)(sin 68) = height =
3.71 m
and the distance of the bottom of the ladder from the wall as follows:
cos 68 degrees = horizontal distance / hypotenuse =
1.50 m
Answer:
The answer is actually A) -8.53
Step-by-step explanation:
The line of best fit has equation y = 2.1x - 0.55, so plugging in x = -3.8 yields -8.53 for y. I just did my USATestprep and this was the answer.
