Answer:
Image result for A triangle has two angles that are 33 degrees and 54 degrees. What is the third angle?
If you add all three interior angle measures together in a triangle it will always equal 180°.. To find a third angle you will subtract the sum of the two given angles from 180°.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let the number be x
<u>Then we have the equation</u>
- (2x + 6)*(-3) = -3x + 54
- -6x - 18 = -3x + 54
- 6x - 3x = -18 - 54
- 3x = -72
- x = -72/3
- x = - 24
Yes they are. if you multiply numerator and denominator of 3/7 by 6, you get 18/42
Using elimination method to find y
3x - 4y = -15 (multiply 4)
4x + 3y = 5 (multiply 3)
------------------------------------
12x - 16y = -60
12x + 9y = 15
--------------------- - (substract)
-25y = -75
y = 3
Using subtitution method to find x
3x - 4y = -15
3x - 4(3) = -15
3x - 12 = -15
3x = -3
x = -1
The solution (-1,3)
