Answer:
x=4,-4
Step-by-step explanation:
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>
Answer:
(E) 27
Step-by-step explanation:
Let the 5 digit palindrome be PQRQP
Since each digit is chosen from 1,2,3 therefore
P can either be 1,2 or 3 which gives us 3 options.
Q can also either be 1,2 or 3 which gives us 3 options
R can either be 1,2 or 3 which also gives us 3 options
So we have 3^3 = 3*3*3
= 27
This means 27 palindromes are possible if they are formed using one or more of the digits, 1, 2, 3.
I believe the answer is 3. Order of Operations is Parenthesis Exponents Multiplication and Division solve left to right and Addition and Subtraction solve left to right
Answer:
Consequently, any trigonometric identity can be written in many ways. To verify the trigonometric identities, we usually start with the more complicated side of the equation and essentially rewrite the expression until it has been transformed into the same expression as the other side of the equation.
