Answer:
X=15
Step-by-step explanation:
Ignore the increase for equasion. This is factored in but irellevent. Orignal x value is 13, but increases to 15, and orignal x value is not needed for this equasion. (its there to confuse you)
L+L+W+W=66.
(w+3) +(w+3) +w +w = 66
(4xw) + 3 +3= 66
4 x w = 66 -3 -3
4 x w =60
60/4= 15.
L= 15+ 3 =18
W = 15.
W + W + L + L
15 + 15 + 18 +18 =66
C is the correct answer
explanation: the opposite is the always the positive or negative of the number
Answer:
C.
Step-by-step explanation:
The minus sign (of the multiplier -1/3) changes the direction of z by 180°. The magnitude of the multiplier 1/3 reduces the magnitude of the product to 1/3 that of z. The graph that has these characteristics is graph C.
That figure obviously doesn't go with this problem. It doesn't matter; this is triangle ABC labeled the usual way.
c = 10, B = 35°, C = 65°
We have two angles and a side. The third angle is obviously
A = 180° - 35°- 65° = 80°
The remaining sides are given by the Law of Sines,
Answer: A=80°, a=10.9, b=6.3, third choice
