Answer:
The area of the swimming pool is 2,847.45ft, assuming this pool is a rectangle.
Step-by-step explanation:
A=l*w
A=23.15*123
A=2847.45ft
Answer:
69°, 69°, and 42°
Step-by-step explanation:
Isosceles triangles have three angles -- one vertex angle and two base angles.
The <u>base angles have the same measure</u> and the vertex angle has a different measure.
<u>Remember all triangles' interior angles sum to 180°.</u>
If the vertex angle is 42°, then the two base angles combined are:
180° - 42° = 138°
Since the base angles are the same, <u>each base angle is:</u>
138° ÷ 2 = 69°
Therefore the angles in the triangle measure 69°, 69°, and 42°.
For the first one it’s x=6.6
And the second one is x=-11
