k = 73
The sum of the angles in a triangle is 180°
sum the 2 given angles and subtract from 180 for k
k = 180 - (62 + 45 ) = 180 - 107 = 73
Answer:
30
Step-by-step explanation:
He draws 40 chips, out of which 12 pink
Probability of pink is 12 out of 40
Making a proportion
12/40= ?/100
? =30
1/50? I can’t be sure....
Ok, so.. first you write both the problems down and write the 10 as a fraction (so it would automatically be 10/1). Then invert so it would be a multiplication problem (1/5 x 1/10). Since you can’t cross cancel, you multiply across. So, 1/5 x 1/10 (1 x 1 and 10 x 5)
1/50
2m+2n+7 is the correct answer
The answer is 12 1/2 or 12.5
