Answer 1

`\huge\boxed{\sf \angle DRY= 134\°}`

Explanation:

Statement:

• Angles on a straight line add up to 180 degrees.

Solution:

∠DRY + ∠YRH = 180°

Given that,

∠DRY = 4c + 118, ∠YRH = 6c + 22

So,

4c + 118 + 6c + 22 = 180

• Combine like terms

4c + 6c + 118 + 22 = 180

10c + 140 = 180

• Subtract 140 from both sides

10c = 180 - 140

10c = 40

• Divide both sides by 10

c = 40/10

c = 4

We know that,

∠DRY = 4c + 118

Put c = 4

∠DRY= 4(4) + 118

∠DRY= 16 + 118

∠DRY= 134°

`\rule[225]{225}{2}`
