Answer:
1) 128°
2) 126°
3) 108°
<h2>
Question one:</h2>
The square in the corner means 90°. If you add the interior angles of any triangle together, you get 180. in this case, x is in exterior angle, so you subtract it from 180 to get the interior angle.
38 + 90 + (180-x) = 180
38 + 90 + 180 - x = 180
38 + 90 + 180 - 180 - x = 0
38 + 90 + 180 - 180 = x
128 = x
<h2>
Question two:</h2><h2>
</h2>
again, adding all the interior angles makes 180°. use this to make the equation.
3x + (5x-6) + 90 = 180
3x + 5x - 6 = 90
8x = 96
x = 12.
x isn't the answer the question wants, however. if you look at the drawing, the angle that's supplementary to 5x-6 is the exterior angle. so,
180 - (5x-6) = the answer
180 - 5x + 6 = the answer
substitute x for 12
180 - 60 + 6 = the answer
126 = x
<h2>Question three</h2>
again, adding all the interior angles together makes 180°.
(a + 10) + 44 + (180-2a) = 180
a + 10 + 44 + 180 - 2a = 180
-a + 234 = 180
234 - 180 = a
54 = a
however, the question is looking for the exterior angle, not a. in this case, the exterior angle is 2a, so just multiply 54 by 2.
x = 108
ABC=50
DCE=65
DEF= I think 115
I hope that helps I would appreciate brainliest if possible :)
Answer:
a = -27
d = -21 - ( -27) => 6
a62 => a + 61 (d) +=> -27 + 61(6)
=> -27 + 366
=> 339
Answer:
The slope would be: -2
Step-by-step explanation:
To find the slope of these two points:
(0,4) and (3,-2)
You would have to use the formula of slope to find it.
The slope formula is:
<h2><u>y₂ - y₁ </u></h2><h2>X₂ - X₁ </h2>
So subsitute in Those two points
(0,4) would be your (x₁ , y₁)
(3,-2) would be your (x₂ , y₂)
So your formula witht he subsituted #'s in it would look like:
<h2><u>-2 - 4</u></h2><h2>3 - 2</h2>
Your answer would be:
<h2><u>-6</u></h2><h2> 3</h2>
Simplified, it is -2
<h3>So your slope is -2</h3>
