Step-by-step explanation:
The formula for the area of the triangle should be ...
A = 1/2bh
Maggie did not use the correct triangle area formula.
Answer:
y = -7
Step-by-step explanation:
To answer this question, we must first plug in -8 for x:
3(-8) + 5y = -59
-24 + 5y = -59
+24 +24
5y = -35
/5 /5
y = -7
Hope this helps :)
To solve this
problem, we must remember that the sum of interior angle of a polygon is:
Sum of
interior angles = (n – 2) * 180˚
So, we can say
that:
Sum of
interior angles = angle A + angle B + angle C + angle D = (4 – 2) * 180˚
Where,
angle C + angle
D = 110 + 70 = 180˚
Therefore
substituting this value:
angle A + angle
B + 180˚ = 2 * 108˚
angle A + angle
B = 360˚ - 180˚
angle A + angle
B = 180˚ (answer)
Hence we can
also conclude that,
<span>angle A + angle
B = angle C + angle D</span>
the answer of it is $2 the original price
