Step-by-step explanation:
800-8p<750
<span>the 6 exterior measures = a, b, c, d, e, f.
Their sum is 360 degrees.
For each one, the interior angle = 180 - exterior.
So for your problem,
a = 55, b = 60, c = 69, d = 57,
e = (missing one)
f = (remaining one, not given).
Take 55 + 60 + 69 + 57 + e, subtract from 360 to get f.
f = 119 - e.
Then the interior angles are:
125, 120, 111, 123, (180 - e), and (180 - 119 + e) = (61 + e).</span>
1 - TRUE
2 - FALSE
3 - 6 or 14
4 - d/t=r
- 9y - 4
factorise the numerator by taking out a common factor of 5y
45y² + 20y = 5y(9y + 4)
The expression now becomes
the 5y on numerator/ denominator cancel leaving
- (9y + 4) = - 9y - 4 ← quotient
