It is valid.
The three angles must add up to 180. So, if one is more than 90, the other two have to be less than 90.
we have to give its answer in degrees .The answer of this question is 45 degree which is between 0 snd 360 degree. i hope u will understand
12/35 is simplified, as you cannot divide it into smaller numbers by a common factor.
I hope this helps!
Answer:
x-intercepts = (x ≈ -0.87), (x ≈ 6.87)
Step-by-step explanation:
let x = 0, in equation for x-intercepts
solve for x using the
quadratic formula
x = <u>−6 ± √ 36 + 24 </u>
2x
= <u>−6 ± √60</u>
−2x
= <u>−6 ± 2 √ 15</u>
−2 = 3 ± √15
(5) Angle ADC is the sum of angles ADB and BDC.
(6) Yes, because lines AG and EC form two pairs of vertical angles, including ADC and EDG, as well as ADE and CDG.
(7) Angle HJK is clearly a right angle, and a right angle has measure 90°.
