ABC= 180 -28 = 152 degrees
Answer:
Step-by-step explanation:
Given equation:
Expand the left side:
Let all terms on the left side have the same denominator of 7:
Join the terms on the left side:
Let all the terms on the right side have the same denominator of 3:
Join the terms on the right side:
Cross multiply:
Expand:
Add 12x to both sides:
Add 252 to both sides:
Divide both sides by 40:
(3 - 2i)(3 + 2i) . Its form is (a - b)(a + b) = a² - b²
( a = 3 and b = 2i)
(3)² - (2i)²
= 9 - (4i²) , but 1² = -1
= 9 - (-4) = 9+4 = 13
So (3-2i)(3+2i) = 13
