Answer:
49, 37
Step-by-step explanation:
Let one number be x and other be y.
According to the first condition:
x + y = 86.....(1)
According to the second condition:
x = y + 12..... (2)
Substituting x = y + 12 in equation (1)
y + 12 + y = 86
2y = 86 - 12
2y = 74
y = 74/2
y = 37
x = y + 12
x = 37 + 12
x = 49
Thus, the two numbers are 49 and 37

Answer:
X=47.68degree
Step-by-step explanation:
tanx=56/51
x=tan^(-1)(56/51)
=47.68
The area of the triangle could be determined by multiplying the length and the width. Since, we are given the area and the length, to find the width, you divide the area by the length:
w = A ÷ l
w = (x2 - 2x - 15) ÷ (x+3)
What do you have to multiply to (x+3) to yield x2 - 2x - 15? That would be x - 5. Since the sum of -5 and 3 = -2 (middle term) and the their product is -15 (last term).
Hence, the width is (x-5).
Im late do you still need the answer aa it wont send aaa
