Mathematics
1 answer:
Ksivusya [100]3 years ago
3 0
L.H.S is already equal, so just subtract 1st equation from second, 
2y = 12
y = 6

Now, substitute it in 1st equation, 
2(6) = 4x + 8
4x = 12 - 8
x = 4/4
x = 1

In short, Your Answer would be Option C) (1, 6)

Hope this helps!

The bases of a trapezoid are 16.8 yards and 6.9 yards. If the height is 2 yards, what is the area of the trapezoid?
Svet_ta [14]
Hello,
Here is the formula to find the area of the trapezoid:
A=1/2(b1+b2)×h
Where b1 represent big base
b2 represent small base
and h represent height
Now, we just need to replace the number to get the final answer:
A=1/2(16.8+6.9)×2
A=1/2(23.7)×2
A=23.7 square yards. As a result, the area of the trapezoid is 23.7 square yards. Hope it help!

In ABC,if sin A=4/5 and tan A=4/3, then what I s cos A?
Svet_ta [14]
Cos(A) will be 3/5 Cos(A) is adjacent/hypotenuse. So here we have sin(A)=opp/hyp which is 4/5 and tan(A)=opp/adj which is 4/3. So cos(A) is adj./hyp and knowing the previous 2 terms of sin(A) and cos(A), you can go ahead and find Cos(A). So cos(A) is 3/5
