Please help in maths all answers.....2i/3-6i
2 answers:
Answer: 45 degrees I think
Step-by-step explanation:
2i / 3-6i
Multiply the top and bottom by the conjugate of 3-6i.
The conjugate is 3+6i
2i(3+6i). Foil = 6i + 12i^2. Or 6i -12 because i^2= -1
(3-6i)(3+6i). Foil. = 9- 36i^2
6i-12 / 9+36
6i-12 / 45
Divide each term by 3
Answer: 2i -4 / 15

Answer:
<h3>Given</h3>
- m∠REG = 78°
- mAR = 46°
- ER ≅ GA
<h3>Solution</h3>
- m∠GAR = 180° - m∠REG = 180° - 78° = 102° (supplementary angles sum to 180°)
- m∠TAR = 1/2mAR = 1/2(46°) = 23° (tangent chord angle is half the size of intercepted arc)
- m∠GAN = 180° - (m∠TAR + m∠GAR) = 180° - (23° + 102°) = 55° (straight angle is 180°)
- mAG = 2m∠GAN = 2(55°) = 110°
- mRE = mAG = 110° (as ER ≅ GA)
- mGE = 360° - (mAG + mAR + mRE) = 360° - (110° + 46° + 110°) = 94° (full circle is 360°)
