Step-by-step explanation:
Answer:
x = 90°
y = 43°
Step-by-step explanation:
We know that one angle equals 47°.
The two triangles are right triangles, so that makes x = 90°.
To find y, we add 90 + 47.
That would give us 137°.
All triangles add up to 180°.
180 - 137 = 43.
43° is the answer.
Answer:
For the first equation
5x-y=74
5(12)-14= 46 which is not =74
Then the second is the equation
Or you calculate it also
3x+y=50
3(12)+14=50
Sutable equation this is
