The answer is 160° . The parallel angles are 180° - 20° is 160° . Hope this helps. :)
Answer:
4x-20 is the same as x+x+x+x-20
Answer:
(3x - 2)*(3x + 2)
Step-by-step explanation:
I don't know how much more i can explain, except that you could use the quadratic formula to get your zeroes and then put it in your answer. But this one is obvious. Whenever there isn't an x term and you're subtracting the constant term, it's usually (ax - b)(ax + b)
Answer is C 66.11>66.10 > 21.10
because 66.11>66.10 and 66.10 > 21.10
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!
