Question 1
cos(C) = adj/hyp
cos(C) = BC/AC
cos(C) = 15/17
Answer: Choice C) 15/17
=============================================
Question 2
sin(E) = opp/hyp
sin(E) = FD/DE
sin(E) = 24/25
So angle E is the answer
=============================================
Question 3
AC is the adjacent side to the given angle A = 33 degrees
AB = 14 is the hypotenuse
cos(angle) = adjacent/hypotenuse
cos(33) = x/14
14*cos(33) = x
x = 14*cos(33)
x = 11.741
x = 11.7
Answer: 11.7
=============================================
Question 4
x = length of board
cos(angle) = adj/hyp
cos(55) = 6/x
x*cos(55) = 6
x = 6/cos(55)
x = 10.46068
x = 10.5
Answer: 10.5
=============================================
Question 5
112 is the adjacent side to the given angle 62 degrees
x = height of building, which is the opposite leg
tan(angle) = opp/adj
tan(62) = x/112
112*tan(62) = x
x = 112*tan(62)
x = 210.641364
x = 210.6
Answer: 210.6
Answer:
-1 degree
Step-by-step explanation:
1.) Subtract 19 from 14.
14 - 19 = -5
2.) Add 4 to -5.
-5 + 4 = -1
Final temperature: -1 degree
Answer:
The correct answer is D) 13%
Step-by-step explanation:
To turn a decimal into a percentage, we simply multiply by 100.
0.13 * 100 = 13%
45% of 76
45%=0.45
0.45*76
34.2
34.2 is about 34
so 34
The difference will be
.
Remember that parentheses are needed for the second polynomial because the negative is distributed to all of its terms.
