14>14 It is incorrect so you can’t have these lengths

2)7+7>15
14>15 X

3)1+2>4
3>4 X

4)3+6>8
9>8

6+8>3

Answer:

m∠1 = mCD = 40°
m∠2 = 1/2(mAB) = 1/2*30° = 15°
m∠3 = 1/2(mED) = 1/2*50° = 25°
m∠4 = 1/2(mAB + mDE) = 1/2(30°+50°) = 40°
m∠6 = m∠OEG - m∠DEG = 90° - 1/2(mDE) = 90° - 25° = 65°
m∠7 = 1/2(mCD + mDE) = 1/2(40°+50°) = 45°
m∠8 = 1/2(mCD + mDE - mAB) = 1/2(40° + 50° - 30°) = 30°
m∠10 = 1/2mAE = 1/2(180° - mDE) = 1/2(180° - 50°) = 65°

Answer:

$52$ roses and $117$ sunflowers

Step-by-step explanation:

Since the ratio of roses to sunflowers is $4:9$ , we can represent how many there are of each as $4x$ and $9x$ , respectively. We know that there are $65$ more sunflowers than roses, so we can set up the following equation to solve for $x$ :
