Answer:
The answer is <em>c</em>
Step-by-step explanation:
If the area of the two triangles are similar, then Area of ∆ 1 : Area of ∆ 2 =
(Side of ∆ 1)² : (Side of ∆ 2)²
____________________________
Since the area of each triangle is equal to the corresponding side squared.
Area of ∆ = (Side of ∆)² →
√(Area of ∆) = Side of ∆ →
Side of ∆ = √(Area of ∆).
Therefore:
9 : 4 → √9 : √4 = 3 : 2
<span>Since angle B and angle C are congruent, angle BDA is a right angle, and the sides of angle B and C have to be congruent, since the angles are congruent, Triangle BDA and Triangle CDA are both congruent, by the Angle-Angle-Side Theorem, which is the criterion that fits this answer.</span>
Multiply the length and height of the paper then divide that by 3 or 3^2 i get confused on that part but pick the answer that makes the most sence
Answer:
The amount of Rita's pocket money left is Rs. 36.
Step-by-step explanation:
Pocket money that Rita had before = 144
Money spent for magazines = 52% of 144
=
= 0.52(144)
= 74.88
Money spent for movies = 23% of 144
=
= 0.23(144)
= 33.12
Money left with Rita = 144 - (74.88 + 33.12)
= 144 - 108
= 36
Hence, Rita left with Rs. 36.
Aliter:
Total money spent = (52 + 23)% = 75%
So, money left with Rita = 100 - 75 = 25%
25% of 144 = 0.25(144) = 36.
