Answer:
y = 46
Step-by-step explanation:
Answer:
x = 17
Step-by-step explanation:
∠6 and ∠7 are vertically opposite angles and thus are congruent, hence
4x = 2x + 34 ( subtract 2x from both sides )
2x = 34 ( divide both sides by 2 )
x = 17
Use x to represent the first two angles. If the third angle is 3 times as large as the first, it can be represented as 3x. So, your angles are x, x, and 3x. These need to all add to 180 degrees, since it’s a triangle.
x + x + 3x = 180 —> Simplify the left side.
5x = 180 —> Divide by 5.
x = 36
So the first two angles are 36 degrees, and the third angle is 3 times that, which is 108 degrees.
