Y=49 degree angle! Because I when you do the math you get that
gavmur [86]3 years ago
6 0

Answer:

angle y = 49°

Step-by-step explanation:

If AB = AD and BC = DC, then the two triangles are isosceles triangles. The altitude from the top to the base divides the top angle into two equal angles, with 90° angles at the base. If angle C is divided into two equal angles (41°) and at the base is a 90° angle, that makes angle CBD 49°. On an isosceles triangle, the two angles opposite to the equal sides are identical. So angle y is identical to angle CBD.

K/5+3-3k=-6k solve ....................
dangina [55]
K/5 + 3 - 3k = -6k
Steps
Subtract 3 from both sides
k/5 + 3 - 3k - 3 = -6k - 3
Then simplify,
k/5 - 3k = -6k - 3
Add 6k to both sides
k/5 - 3k + 6k = -6k - 3 + 6k
Simplify,
k/5 + 3k = -3
Next, multiply both sides by 5
k/5 * 5 + 3k * 5 = -3 * 5
So,
k + 15k = -15
16k = -15
Then, divide both sides by 16
16k/16 = -15/16
Simplify,
k = -15/16
