Which postulate or theorem proves △FWJ∼△PKJ ?
artcher [175]

AA Similarity Postulate - we get the triangle on the left's angles; 90 and 63, and we subtract from 180.

180 - 90 - 63 = 27

So we have angle measures 27, 63, 90

For the triangle on the right, with measures 27 and 90, we use the same  idea:

180 - 90 - 27 = 63.

You'll see that we also have 27, 63, 90.

Triangles with the same angles are defined as similar, so AA should be the answer

What is the volume of the cone with radius 5 m and height 6 m? Express the answer in terms of π.
ra1l [238]

The formula of a volume of a cone:

V=\dfrac{1}{3}\pi r^2H

We have r = 5m and H = 6m. Substitute:

V=\dfrac{1}{3}\pi(5^2)(6)=\pi(25)(2)=50\pi\ m^3

Jason inherited a piece of land from his great-uncle. Owners in the area claim that there is a 45% chance that the land has oil.
Zina [86]
If owners told the truth, then the probability is always the same: 0,45.
0,45*0,80 = 0,36

Supposing trust your kit only, then there was 0,8 probability for correct measurement, meaning there is 0,2 chance for incorrect measurement.
If incorrect measurement means displaying a result opposite then truth, then there is 0,2 probability for oil.
If incorrect measurement means displaying a random result (assuming distribution of correct (by fortune) or incorrect answers is 50-50), then there is 0,2*0,5 probability for oil. That is 0,1 probability for oil.

If somehow the answer you are looking for consists of believing the owners and the kit equally, then there are two options. You get both options by applying 0,45 chance to results from previous two cases.
First solution would be 0,2*0,45, that is 0,09 chance.
Second solution would be 0,1*0,45, that is 0,045 chance.

Since none of these answers matches any of given options, I am really interested in calculations by other people. Please do correct me if I made a mistake in my calculations.
