Answer:
7.
This is a complementary angle, which means that the two angles add up to 90 degrees. The two angles, in this case, are b and 52. Thus, we have:
b + 52 = 90
b = 38.
Therefore, b is 38 degrees.
8. This is a supplementary angle, which means that the two angles add up to 180 degrees. There is a right angle in the picture to confuse us, so we can just pretend that that doesn't exist, and just focus on the 180-degree angle (which is the straight line). The two angles shown are b and 117, so we have:
b + 117 = 180
b = 63
Therefore, b is 63 degrees.
9. This is a supplementary angle, which means that the two angles add up to 180 degrees. There is another line in the picture to confuse us, so we can just pretend that the line that is making a triangle (the one opposite of 125 degrees) doesn't exist, and just focus on the 180-degree angle (which is the straight line). The two angles shown are b and 125, so we have:
b + 125 = 180
b = 55
Therefore, b is 55 degrees.
Answer:
the area of the garden is 187
Step-by-step explanation:
Answer:
Length is 8 feet
Width is 28 feet
Step-by-step explanation:
We can think of this as "parts" problem.
- If the ratio of length to width is 2 to 7, we can say that the total parts is 2 + 7 = 9
- We also know that the measurement of Length + Width is 36 ft.
There are 9 parts in total and it is 36 feet. Hence, 1 part is:
feet
<em><u>From initial ratio statement, we know length is 2 parts and width is 7 parts.</u></em>
Length is feet
Width is feet
Answer:
the amount spent on petrol is Rs 9,676
Step-by-step explanation:
Given that
The tax driver filled the car petrol with 54 liters on Saturday
On sunday, he filled his tank with 64 liters
And, the petrol cost is Rs 82 per liter
We need to find out the amount of money spent
SO,
= (54 liters + 64 liters) × Rs 82
= Rs 9,676
Hence, the amount spent on petrol is Rs 9,676
