Help plzzzzzzzz do these two questions and I’ll mark Brainlynest
marin [14]

Answer:

Step-by-step explanation:

Q1: <B = 150 °

If two parallel lines are cut by a transversal, then alternate interior angles are congruent.

8x-10 = 3x+90

5x=100 (subtract 3 from both sides)

x=20   (divide both sides by 5)

x = 20

<B= 3x +90

<B = 3 (20) +90

<B = 60 + 90

<B = 150

Q2: 62

An angles complement (not compliment, haha) is what the number that added to the angle equals 90°.

An angle is 34 more than its complement.

Let x represent the angle.

Let y represent its complement.

x= 34 +(90-x)

y= (90-x)

x + y = 90

34 + (90-x) + (90-x) =90

x= 62

Check the answer.

x= 34 more than complement.

62-34=28

62+28=90

Checked!

Words of encouragement:

Good luck!

natka813 [3]

Answer:

Step-by-step explanation:

cost \ price = X\\Deduction = P \%\\Deduction \ Price = P \% of X = \frac{P}{100} \times X = \frac{XP}{100} \\\\Cost \ price \ after  \ deduction  = X -\frac{XP}{100}

OR SIMPLIFY FURTHER
