Since a right triangle has one known angle (90°) and the sum of a triangles interior angles are 180°, you can take a given angle (like 36°) and add it to 90° and then subtract 180 from it.
Essentially, do the following:
A = 90-givenAngle
A = 180- ^^^^^^^^
The probability that a randomly selected pigeon gets an incorrect result is; 0.0103
<h3>How to find the Probability?</h3>
We are told that;
1.5% pigeons are infected.
Inaccuracy of the test = 1 - 97% = 3%
1.5% of the pigeons are infected. Thus;
1 - 1.5% = 98.5% pigeons are un-infected.
Inaccuracy of test is 1 - 99% = 1% .
Thus;
0.03 and 0.01 are the probability of an error being made in infected and un-infected respectively.
Meanwhile, probability of infected and un-infected are 0.015 and 0.985 respectively.
Thus, the probability of a randomly chosen person gets an incorrect result = (0.03*0.015) + (0.985*0.01) = 0.0103

The first part is addition.
45+m
If she spend a third of it, you could multiply by 1/3 or divide by 3.
Multiply: 45+m x 1/3
Divide: 45+m/3
Add 4x
to both sides of the equation.
a. y=4x+6
Add 5x to both sides of the equation.
b. y=5x+21
