Answer:
180, 180, 148, 180, 148
Step-by-step explanation:
The two rules in play here are ...
- the sum of interior angles of a triangle is 180°
- the angles of a linear pair are supplementary (they total 180°)
__
The first of these rules answers the first two questions:
- interior angles total 180°
- angles 1, 3, 4 total 180°
We can subtract the measure of angle 1 from both sides of the previous equation to find the sum of the remaining two angles.
- angles 3 and 4 total 148°
The second rule answers the next question:
- angles 1 and 2 total 180°
As before, subtracting the value of angle 1 from both sides of the equation gives ...
_____
<em>Additional comment</em>
Of course, the subtraction property of equality comes into play, also. For some unknown, X, you have (in both cases) ...
X + 32° = 180°
X +32° -32° = 180° -32° . . . . . . subtraction property of equality
X = 148° . . . . . . . . simplify
In the first case, X is the sum of angles 3 and 4. In the second case, X is angle 2 only.
1/6*6 is 1, so we can say that 3*6 is 18.
So, the part will be 18 inches in real life.
Answer:
x=2 1/4
Step-by-step explanation:
Let's swap it around so its 1/3(8x+3)=7
Now you multiply both sides by 3 to make it 1(8x+3)=21
That means its 8x+3= 21
Subtract both sides by 3 to get rid of it
Now you have 8x=18
Which equals to x= 18/8
Which equals 2 1/4
Answer:
5.005
try that, im pretty sure you subtract
