Answer:
Sin 90°=1
Step-by-step explanation:
A unit circle is a circle with a radius of 1 .Because the radius is 1, it is possible to directly measure the sine, cosine and tangent.
<em>using the unit circle where 90° is the limit as the hypotenuse approaches the vertical y-axis which is positive.</em>
Sine=opposite/hypotenuse
Sin=O/H
<u>Applying the limits</u>
Sine 90°=1/1= 1
cos 90° =0/1 =0
or
When the angle formed at the origin of the unit circle in the 1st quadrant is 0°, cos 0°=1 sin0°=0 and tan 0°=0
When we increase the angle until it is 90°, cos 90°=0, sin 90°=1 and tan 90°=undefined
Step-by-step explanation:
Since Angle DAE = Angle BCE, lines AD amd BC are parallel (by Z-angles).
This means that Angle ADE = Angle CBE (by Z-angles).
We have 2 congruent angles and 1 congruent side (AD = BC, given).
By ASA congruence, triangles AED and CEB are congruent.
Answer:
- Equilateral Triangle
- Right angle triangle
- Isosceles triangle

Answer:
1.5 is the asnwer because when you multiply first image by 1.5 you get the second.
Answer:
415$
Step-by-step explanation:
This might seem a bit confusing, and the best thing you can do is simplfy this and pick out all the important information. Here is what I gathered:
So, we know we need 200$.
We also need 115$.
Then we need 100$..
To find how much money we need in total, lets add these all up:
200+115
=
315
315+100
=
415
So the total money we need is 415!
Hope this helps!
