Answer:
A=80 , B=65, C=35
Step-by-step explanation:
A-B=15 ⇒A=B+15
B-C=30⇒-C=30-B ⇒C=B-30
the sum of angle of a triangle = 180
A+B+C=180 ( substitute A and C)
B+15+B+B-30=180
3B-15=180
3B=180+15
B=195/3=65
C=B-30 ⇒ C=65-30=35
A=B+15=65+15=80
check : A+B+C=180
80+65+35=180 ( correct)

Answer: 20 cm
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain a variable.
<u>Solution</u>:
It is given that length of a rectangular room is 6.9 m and its width is 9.6 m.
So We have ;
- Length of Rectangular room = 6.9 m
- Length of Rectangular room = 6.9 m Width of Rectangular room = 9.6 m
<u>So We have to find the area of the room.</u>
We know :
<h3>Area of Rectangle = Length times Width </h3>
<u>Area of Rectangular room = Length of Rectangular room × Width of Rectangular room </u>
Area of Rectangular room = 6.9 m × 9.6 m
Area of Rectangular room = 6.9 m × 9.6 m Area of Rectangular room = 66.24 m²
Therefore, Required area of the room is 66.24 m².
