Answer:
O = 41 degrees
Step-by-step explanation:
the sum of all angles in a triangle is always 180 degrees.
the graphic shows that this triangle has 2 equal sides. that means that both angles at O and at M are equal.
so, we know all three angles and can calculate
7y + 2×(4y - 15) = 180
7y + 8y - 30 = 180
15y = 210
y = 14
so, the angle at O is
O = 4×14 -15 = 56 - 15 = 41 degrees
Answer:
B = 
A
Step-by-step explanation:
Given that B varies directly as A then the equation relating them is
B = kA ← k is the constant of variation
To find k use the condition A = 90 and B = 40, then
k = 
= 
=
B = A ← equation of variation
I believe the answer is 66, because the full length of the side on the left is 13, if you subtract 13 by the 6 on the right, then you’ll have 7, then if you subtract 8 from 20 you’ll have 12. If you add 20+13+12+8+6+7 it equals 66
