Answer:

Below in bold.

Step-by-step explanation:

The sine is positive in the first and second quadrants and negative in other 2.

The cosine is positive in the first and 4th quadrants and negative in other 2.

Note that sin(pi/6) = 1/2 and cos(pi/3 = 1/2).

sin(7pi/6) = 1/2  

cos(5pi/3) = 1/2

sin(5pi/6) = 1/2

How do you find the ratio of x and y coordinates
Firdavs [7]

Answer:

(in step-by-step explanation)

Step-by-step explanation:

The ratio x:y is the same as the fraction x/y  if that helps, so it is basically putting the coordinates into a fraction. Here is a video that might help also: https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-ratios-prop-topic/cc-6th-ratio-word-problems/v/ratios-on-coordinate-plane

Coordinate planes are a way of expressing data, so if it makes it easier, put the data into a ratio! Sorry, it is a bit difficult to explain such a broad question.

Based on only the information given in the diagram, which congruence postulates or theorems can be given as reasons why triangle
Lapatulllka [165]

Let's go through the choices.

A. HL, hypotenuse-leg. Yes we have a right triangle with congruent hypotenuse and leg which gives us congruent triangles, CHECK

B. HA, hypotenuse actute. Yes we have a right triangle witha congruent hypotenuse and acute angle, so congruent triangles, CHECK.

C. LL. leg leg. We don't know HL=PE so we can't use this theorem here. NO.

D. SAS, side angle side. For this one we first have to prove angle HEL is congruent to angle PME which is easily done with the Triangle Angle theorem (two congruent angles means three congruent angles) and then we can use SAS because then we have congruent sides and a congruent included angle. This one's a judgement call, I'll say NO because of the two steps.

E. AAS. Angle Angle Side, yes we have two congruent angles and a side. CHECK

F. ASA. Again we need an additional step before we conclude two angles and an included side are congruent. So again a judgement call, we'll go with NO.
