A.The sum of two products; there are two terms
Answer: Its surface covers 1400 cm²
Explanation:
Since the length of painting = 40 cm
Breadth of painting = 35 cm
Since we know that area of rectangle is product of dimensions.
∴ Area of painting = length × breadth
= 40 cm × 35 cm
= 1400 cm²
∴ Its surface cover 1400 cm².
5+5=10 and 15-5=10..........
Answer:
20 degrees
65 degrees
95 degrees
Step-by-step explanation:
Add the numbers in the ratio.
4+13+19=36
Divide the sum of all the angles in a triangle by the sum of the numbers in the ratio.
180/36=5
Multiplying 5 to each of the numbers in the ratio will give the measures of the angles.
4(5)=20 degrees
13(5)=65 degrees
19(5)=95 degrees
