Answer:
3
Step-by-step explanation:
First of all, the area in a triangle adds up to 180.
Secondly, it's an equilateral triangle, so all 3 angles are the same. Therefore, all 3 angles must equal 180/3 = 60.
Angle B - 25x - 15 = 60
Rearrange to get x on it's own.
25x - 15 = 60
25x = 60 + 15
25x = 75
Divide by the coefficient to find x.
25x = 75
x = 75/25
x = 3
2a^3-4a^2+5a+3
Explanation:
For standard form you always start with the one that has the biggest exponent to the least one
ANSWER
EXPLANATION
The diagonals of a parallelogram bisects each other.
Therefore
This implies that,
We make x the subject to get,
Similarly,
This implies that,
We substitute equation (1) in to equation (2) to get,
We expand the bracket to get,
We group like terms to get,
Divide both sides by 4 to obtain,
We put the value of y into equation (3) to get,
