Step-by-step explanation:
Answer:
X
Step-by-step explanation:
Mathematically, the tangent of an angle is the ratio of the opposite side to the adjacent side
So, for 20/22; 20
is the opposite while 22 is the adjacent
The opposite side simply refers to the side that faces the given angle
We have the opposite side here as facing the angle X and that makes X the correct answer
Answer:
x = 61
Step-by-step explanation:
The two angles add to a right angle, which is 90 degrees
29+x = 90
Subtract 29 from each side
29+x-29 = 90-29
x = 61
45.(2x-4)+ 5x; [2x+5x]-4; 7x-4
46. 0.4b-3.2+1.2b; [0.4b+1.2b] -3.2; 1.6b -3.2
47. 1/4g+6g- 2/3 6 1/4g -2/3
48. -12 -14= -26 the temperature was -26C at 11:00pm
9514 1404 393
Answer:
a) $2.40
b) $16.80
c) y = -2.40x +16.80
Step-by-step explanation:
a. Dylan's daily spending is the opposite of the slope of the line on the graph. That slope can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (4.8 -12)/(5 -2) = -7.2/3 = -2.4
Dylan spends $2.40 at lunch every day.
__
b. The y-intercept can be found from the formula ...
b = y1 -m(x1)
b = 12 -(-2.40)(2) = 16.80
Dylan's dad gives him $16.80 at the beginning of each week.
__
c. The slope-intercept equation is ...
y = mx + b
y = -2.40x +16.80
