145+67=212 One other way to solve it is to solve it is you subtract.
Answer:
a would be 12
Step-by-step explanation:
because there are 5 1's so you would subtract 5 from 65 and get 60 and divide 60 by 5 and get 12

YaYYYY u got it!!!! =)
Answer: The correct answer is (C) 8.8
Step-by-step explanation: The given triangle has two sides and two angles given. However it is not a right angled triangle. In order to calculate an unknown side or angle in questions such as this, we shall apply the sine rule, which states;
a/SinA = b/SinB = c/SinC
Where the reference angle is that facing the line (that is, SinA is the angle facing line a, etc).
To calculate x, we shall use angle 28 as the reference angle. We have also been given line 8.2, and the angle facing it is derived as
180 - (28 + 126)
= 180 - 154
= 26
If the angle facing line 8.2 is 26, then the sine rule can be applied as follows;
x/Sin28 = 8.2/Sin26
By cross multiplication we now have
x (Sin26) = 8.2 (Sin28)
x = [8.2 (Sin28)]/Sin26
x = (8.2 x0.4695)/0.4384
x = 8.7817
Approximately x = 8.8 (to the nearest tenth)
