The measure of angle A will be 61°
The sum of A and B is 122°
The sum of A B and C is 151°
<h3>How to calculate the angle?</h3>
It should be noted that complementary angles have an angle of 90°.
Therefore, the value of A will be:
= 90° - 29°
= 61°
The value of B will be:
= 90° - 29 = 61°
The value of A and B will be:
= 2 × 61°
= 122°
The value of A B and C will be:
= 122 + 29
= 151°

The balanced chemical reaction is:
<span>Ca(OH)2 + 2 HCl = 2 H2 O + CaCl2
</span>
We are given the amount of hydrochloric acid to be used in the reaction. This will be the starting point for the calculations.
0.124 mol HCl / L soln ( .0375 L solution) ( 1 mol Ca(OH)2 / 2 mol HCl) / 0.020 L Ca(OH)2 solution = 0.12 mol / L Ca(OH)2 = 0.12 M
Answer: y = -3/4x + 7
Step-by-step explanation:
first find slope:
y2-y1 / x2 - x1
1-4 / 8-4
-3/4
now just plug the slope (m) into the equation of a line using one of the points to find the y intercept
ill use (8,1)
1 = (-3/4)(8) + b
now solve :)
1 = -6 + b
7 = b
so now plug in the slope and the y intercept into the slope intercept form to find the equation of the line
y = -3/4x + 7
Answer:

Step-by-step explanation:
As the numbers are only between 1 and 30
Total number of possible combinations = 30×30×30 = 27000
If there are 100 attempts then

∴ Probability someone can guess the correct combination given 100 attempts is
