Answer:
44.1 mm^2
Step-by-step explanation:
The formula for a trapezoid is 1/2(b1 + b2)h
A= 1/2(12.5 + 8.5) 4.2
= 1/2x21x4.2
=44.1
We know: the sum of measures of triangle angles is 180°.
Therefore we have the equation
Substitute 
:
<h3>Answer: 180 - 7x</h3>
Let the third angle = x
It would be: 35 + 45 + x = 180
80 + x = 180
x = 180 - 80
x = 100
So, your final answer is 100
Hope this helps!
Answer:
y = 2x + 5
Step-by-step explanation:
First,
9-3 = 6
over
2-(-1) = 3
Then,
6 divided by 3 = 2
2 = slope
Next, using (-1,3), *you can use either ordered pair
y - 3 = 2 {x - (-1)}
y - 3 = 2x + 2
y = 2x + 5
