Subtract normally as if 32.6 is 316 and 1.9 is 19. Then you move the decimal point two places to the left of the answer
the answer is 29.7
Supplementary means they add up to 180
angle 1 = x
angle 2 = x + 166
so x + x + 166 = 180
2x = 14
x = 7
so angle 1 = 7 angle 2 = x + 166 = 173
The size of the angle would be : 150 degrees
Answer:
n = 13
Step-by-step explanation:
Given
n - 26 = - 13 ( add 26 to both sides )
n = 13
The area covered by the canal in 30 mins is 562500 sq m
Step-by-step explanation:
Step 1 :
Given,
The canal's width = 6 meter
The canal's Depth is given as 1.5 meter
Speed of the water flowing = 10 kilometer per hour
We need to determine the area which will be irrigated in 30 mins
Step 2 :
In one hour the canal flows 10 kilometer , therefore in 30 minutes it covers 5 kilometer = 5 ×
meter
Hence the volume of the water irrigated per 30 minutes = 6 × 1.5 × 5 ×
= 45 ×
cubic meter
The standing water is 8 centimeter = 8 ×
meter
Hence the area covered in 30 min = Volume ÷ the height of the standing water
= (45 ×
) ÷ 8 ×
meter
= 562500 square meter
Step 3 :
The area covered by the canal in 30 mins is 562500 square meter
