Question

Another one im straight bad at math yall

Answer 1

60°

Explanation:

substitute x=25 into 2x+10

2(25) + 10= 60

alternatively,

180°-120°= 60°

Answer 2

`\huge\boxed{\sf \angle 2 = 60\°}`

Explanation:

From the given figure:

5x - 5 + 2x + 10 = 180° (Angles on a straight line)

• Combine like terms

5x + 2x - 5 + 10 = 180

7x + 5 = 180

• Subtract 5 from both sides

7x = 180 - 5

7x = 175

• Divide both sides by 7

x = 175/7

x = 25

We know that,

∠2 = 2x + 10

Put the value of x

∠2 = 2(25) + 10

∠2 = 50 + 10

∠2 = 60°

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