Answer:
8.9
Step-by-step explanation:
Parenthesis are always first so,
4.5+7.6=12.1
so the problem would look like this now:
12.1-8/2.5
so convert 8/2.5 to 8÷1/5÷2 so this will become 16/5
16.5 concerted to decimal=3.2
so 12.1-3.2=8.9

Final answer:
In a right triangle, sin A equals cos B because A and B are complementary angles. Sin A cannot equal tan A, tan B, or cos A.
Explanation:
In a right triangle, the sine of an angle is defined as the length of the opposite side over the length of the hypotenuse. Therefore, sin A cannot be equivalent to tan A or tan B because tangent of an angle is the ratio of the opposite side to the adjacent side. The sine of angle A is not related to cos A because cosine of an angle is the length of the adjacent side over the length of the hypotenuse.
However, it's relevant to note that in a right triangle, the sine of an angle is equal to the cosine of its complementary angle. Since A and B are complementary angles in a right triangle (sum up to 90 degrees), it means that sin A equals cos B. So, the correct answer is C: cos B.

The required simplified value of a is 1/2 .
Given that,
3 +0.5(4a + 8) = 9 – 2a
The simplified value of a is to be determined.
What is arithmetic?
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
What is simplification?
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
3 +0.5(4a + 8) = 9 – 2a
3 + 0.5*4a + 0.5*8 =9 - 2a
3 + 2a + 4 = 9 - 2a
7 - 9 = - 4a
a = 1 / 2
Thus, the required simplified value of a is 1/2.
