Answer: 21.3m
Step-by-step explanation:
The height of the kite of the ground would be calculated as:
We have to calculate the question using a right angled triangle that has angle ACB as 90° while angle CAB will be 40°.
Therefore, the height of the kite would be:
= 30 sin 40 + 2
= 30 (0.6428 ) + 2
= 19.284 + 2
= 21.284 m
= 21.3 m
2a+3b=82
a+b=38
These are the two equations you need to solve for a and b
x = [-3 +/- √(3^2 - 4*1*2) ] / 2
= [- 3 + √( 1)] / 2 , [- 3 - √( 1)] / 2
= -2/2 , -4/2
= [-1, -2} answer
Answer:
Step-by-step explanation: it is 2
And that is the Answer
Answer: 12r + 3
Step-by-step explanation:
6r+3(2r+1)
Apply BODMAS, do bracket first
6r + (6r + 3)
Do addition next
= 12r + 3
