As the sum of two complementary angles = a + b = 90
degree -------(1)
Difference of two complementary angles = a – b
According to question;
The difference of two complementary angles exceed the
sume (90) by 86.
So
a – b = 90 – 86 = 4 -------(2)
adding equation (1) and (2);
2a = 90 + 4 = 94
a = 94 / 2 = 47
putting a = 47 in equation (1);
47 + b = 90
b = 90 – 47 = 43
<span>
So angle a = 47 and
angle b = 43</span>

Step-by-step explanation:
Distance = the square root of (x2-x1)2 + (y2-y1)2Added:Distance Formula: Given the two points (x1, y1) and (x2, y2), the distance between these points is given by the formula:square root of x2-x1 squared +y2-y1 squared
Answer:
Step-by-step explanation:
MA²=MX²+AX²
=20²+21²
=400+441
=841
MA=√841=29
2.5 pounds of apples * $1.20 = $3
He spent total $4.50
So he had to have spent 1.50 on oranges.
So $1.50=$1.20 x where x will be the pound of oranges bought.
1.50/1.20 = 1.25 or 1 1/4 pounds of oranges.
