Sum of the interior angles of a pentagon is 720 degrees. Sum of two angles that form a bisected line is 180 degrees. So interior angles going clockwise are 138 degrees. 128 degrees. 119 degrees. 180- 2*t degrees. And 180 - 3*t degrees. So sum of angles is:
138+128+119+(180 - 2*t) + (180 - 3*t) = 720
25 = 5*t
t = 5 degrees.
Answer: The answer is 24a + 6 because you add up the like-terms, so:
18a + 6a = 24a
8 - 2 = 6
I hope this helps!
Step-by-step explanation:
Answer:
y = x^2 + 8x - 3
y = x^2 + 8x + (8/2)^2 - 3 - (8/2)^2
y = x^2 + 8x + 16 - 3 - 16

Answer:
75.5 % of all candidates passes
Step-by-step explanation:
36000 x .45 = 16200 x .7 = 11,340 girls passed
36000 x .55 = 19800 x .8 = 15,840 boys passed
total of boy and girls who passed = 27,180
27,180 out of 36,000 equals 75.5%
