Answer:
It is a right triangle.
Step-by-step explanation:
A right triangle is a triangle with at least one angle with 90 degrees.
We know that every triangle has 180 degrees. The other unknown angle is 180 - (30+60) = 180 - 90 = 90. That means that the other angle is 90 degrees. Therefore, it is a right triangle
We also know that in this triangle, that the square of one side plus the square of another is side is equal to the square of the hypotenuse of the triangle. (According to Pythagorean theorem)
Since angles 3 and 4 are supplementary, they add up to 180 degrees.
Angle 3 is 88 degrees.
To get the measure of the last angle, let's subtract 88 from 180.
180 - 88 = 92
Thus, Angle 4 has a measure of 92 degrees.

It is C, "What type of paper are most greeting cards made with."
The probability of a car crash is 56.75
Approx probability of car crash = 227/400 = 0.5675 i.e. 56.75%
This probability is high enough to be of concern to those in the 16-18 age bracket because the probability is not unlikely.
Probability is the department of mathematics concerning numerical descriptions of the way in all likelihood an occasion is to occur, or how probable it's miles that a proposition is actual. The probability of an occasion is more than a few between zero and 1, in which, kind of talking, 0 indicates impossibility of the occasion and 1 shows actuality.
The probability of an occasion can be calculated through chance system via simply dividing the favorable range of results by using the overall number of possible results.
