Answer:
120 = 28 + 12(½) + X
Where X is the no. of pages of articles
120 = 28 + 6 + X
X = 120 - 34
X = 86
Answer:
Second one
Step-by-step explanation:
They have one angle (R) in common
Also,
Angles T & S and P & Q are equal because they are corresponding angles.
RS/RT = SQ/TP
4/(4+4) = 2x/(x+6)
4x = x + 6
3x = 6
x = 2
SQ = 2(2) = 4
TP = 2 + 6 = 8
Answer:

Step-by-step explanation:

Answer: 0.99
Step-by-step explanation: sin 90 Divided by 85 = sin x divided by 13
sin x =13x sin 90 divided by 85
sin x = 13divided by 85
sin x = .152941176
arc sine of .152941176= 8.79741071 degrees
cos 8.79741071 = .988235294
.99
