Congruent sides, so isosceles triangle. When we have an isosceles triangle the bisector of angle A is a perpendicular bisector of BC with foot D. So x=ADB=90 degrees.
Angle B is 47 degrees and angle y=BAD is complementary, the other acute angle in a right triangle.
y = 90 - 47 = 43
Answer: x=90, y=43

what grade r u in btw ?
Anita can clean 1/8 portion of the pool in 1 hour
Chao can clean 1/6 portion of the pool in 1 hour
Both of them working together can clean 1/8 + 1/6 = 7/24 portion of the pool in 1 hour
Therefore, it will take both of the working together 1/(7/24) = 24/7 or 3 3/7 hours to clean a typical pool.
Let the smaller angle be x.
smaller = x
larger = 3x
known angle = 65°
All angles add up t10 180:
x + 3x + 65 = 180
4x + 65 = 180
4x = 115
x = 28.75
Smaller angle = 28.75
Larger angle = 86.25
Answer: The angles are 28.75° and 86.25°
Answer:
In order to solve this algebraic expression, you need to get the variable x by itself
Step 1: subtract 4 from each side
4-4+7x=-24-4 (4-4=0, those cancel out) (-24-4=-28)
7x=-28
Step 2: divide both sides by 7
7x/7=-28/7 (7x/7=x) -28/7=-4)
Your final answer would be x=-4
Hope this helps ;)
