Find the values of x and y.
1 answer:
Step-by-step explanation:
Hey there!!!
When you closely see in figure, we find that,
90° and (2y + 5)° are supplementary,
So, 90° + 2y +5°=180° { supplementary angle is always 180°}.
or, 2y = 180°-95°
Therefore the measure of angle y is 42.5°.
Again, (5x-17)° + (3x - 11)° = 180° (They are linear pair).
8x - 28° = 180°
8x = 180°+28°
Therefore the measure of angle x is 26°.

Answer:
<h2>x = 5.7</h2>Step-by-step explanation:
To find x first cross multiply
We have
7x = 8 × 5
7x = 40
Divide both sides by 7
That's
x = 5.7142
We have the final answer as
<h3>x = 5.7 to the nearest tenth</h3>Hope this helps you
Here we have to find the probability . Now express the probability in terms of standard normal cumulative distribution function. That is

Now you can look up the probability from the standard normal tables. Its value is
Alright , lets get started.
A polynomial can have constants, variables or exponents that can be combined using addition, subtraction, multiplication and division but not division by a variable.
