Remember, these are quadrilaterals, so they must add up to 360°. Just add up the angles and then do 360 minus that number to solve for x.
Therefore:
1. 118 + 90 + 99 = 307
360 - 307 = 53
2. 110 + 96 + 78 = 284
360 - 284 = 76
3. 48 + 118 + 97 = 263
360 - 263 = 97
4. 105 + 99 + 64 = 268
360 - 268 = 92
5. 103 + 63 + 113 = 279
360 - 279 = 81
6. 95 + 80 + 88 = 263
360 - 263 = 97
H= 79
add 7 to both sides.
Answer:
2nd option = 3 is the answer.
I would minus 2 from both sides of the equation so that it becomes:
Answer:
q12 is 8
q13 is 81
Step-by-step explanation:
100*6 =600 / 75 = 8
90*72 = 6480 / 80 = 81
