(0.75 * 3.5a) + (0.75 * -6b) = 2.63a -4.5b
Answer:
389 feets apart
Step-by-step explanation:
Given that:
Building A
Height = 400feets
Angle of elevation = 70°
Building B:
Height = 300 feets
Angle of elevation = 52°
Distance from the foot of building A to where Jonny is standing = x (see attached picture)
Using trigonometry :
Tanθ = opposite / Adjacent
Tan 70 = 400/ x
2.7474774x = 400
x = 145.58809 feets
Distance from the foot of building B to where Jonny is standing = y (see attached picture)
Using trigonometry :
Tanθ = opposite / Adjacent
Tan 52 = 300/ y
1.2799416y = 300
y = 145.59
y = 234.38568 feets
x + y = distance between the two buildings
(145.58809 + 234.38568) feets
= 379.97377
= 380 feets apart
Answer:
Rs. 5500
Step-by-step explanation:
The government has declared that farm workers should be paid Rs. 71 for a day's work
The landlord Mohan pays Rahul Rs. 60 and pays Rs. 55 to his wife
Rahul works for 55 days
= 60 × 55
= Rs. 3,300
His wife works for 40 days
= 55 ×40
= Rs. 2,200
Therefore the total amount of money earned together can be calculated as follows
= 3300 + 2200
= Rs. 5500
Hence they will earn Rs. 5500 together
Y= -2+4
If X equals -2, you want to plug -2 in for X.
I hope I helped!
