In the given quadrilateral ABCD ,
- Angle BCA = 18°
- Angle ACD = 62°
Angle BCA = Angle CAD ( alternate interior angle )
Now in triangle CAD ,
We have two angles so by using angle sum property we can find the required third one ,
- Angle CAD + Angle ACD + Angle ADC = 180°
- 18 + 62 + Angle ADC = 180
- 80 + Angle ADC = 180
- Angle ADC = 180 - 80
- Angle ADC = 100
Answer:
∠ ADC = 100°
Step-by-step explanation:
∠ CAD = ∠ BCA = 18° ( alternate angles )
The sum of the 3 angles in a triangle = 180° , then
∠ ADC = 180° - (62 + 18)° = 180° - 80° = 100°

80 since he starts off with 38 stamps then gains 6 each month for 7 months (6x7=42) so 42+38=80
Given:
- The area of a rectangular painting is 7719 cm²
- Width of painting = 83cm
To Find?
Solution:
- Let length of painting be x cm
Using formula:
- Area of rectangle = L × B
Where,
- Length = x cm
- Breadth = 73 cm
→ 7719 = x × 83
→ x = 7719/83
→ x = 93 cm
Hence,
- Length of painting is 93cm
Answer:
A
Step-by-step explanation:
You can multiply both sides on an equation by the reciprocal to cancel the fraction on the first side.
