10 + 12 + 23 ÷ 3 = 15
22 + 23 ÷ 3 =15
45 ÷ 3 = 15
The missing number would be 23 since 22 + 23 is 45 and 45 divided by 3 is 15.
Hope this helped :)
Answer:
The sin(A) goes with 'a'
sin(B) goes with b
sin(C) goes with c
Each angle goes with the corresponding side to form the three fractions shown. You can break up that triple equation into smaller equations such as and and
Note: if you apply the reciprocal to all three sides, then you'll get an equivalent equation. I'm using the rule that A/B = C/D is the same as B/A = D/C.
Answer:
Kiran is wrong, I don't agree
Step-by-step explanation:
-5 has less value than -2 and -2 is larger than -5.
<u>Answer </u><u>:</u>
In the given quadrilateral ABCD ,
- Angle BCA = 18°
- Angle ACD = 62°
Angle BCA = Angle CAD ( alternate interior angle )
Now in triangle CAD ,
We have two angles so by using angle sum property we can find the required third one ,
- Angle CAD + Angle ACD + Angle ADC = 180°
- 18 + 62 + Angle ADC = 180
- 80 + Angle ADC = 180
- Angle ADC = 180 - 80
- Angle ADC = 100
