False I think
sorry if im wrong
500•1.1= 550, 320•1.1= 352, 80•1.15= 92, 75•1.25= 93.75
Answer:
x = 23
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
the third angle forms a straight angle with 100°, hence
third angle in triangle = 180° - 100° = 80°
Summing the 3 angles gives
2x + 3 + 80 + 51 = 180
2x + 134 = 180 ( subtract 134 from both sides )
2x = 46 ( divide both sides by 2 )
x = 23
Answer:
40
Step-by-step explanation:
28 divided by 7= 4 (to get the number of 1/10)
4 x 10= 40
Ok, you are given a point and you need to find the exact values for
First thing first. We need to see if we are working with a unit circle and find the radius.How to tell if we are working with a unit circle?We know
is a circle.
We know that to find the radius we can use the following formula:
If
we are working with a unit circle.
Lets see if it = 1.
Square both sides nowSince we squared, we have a + and a - but we disregard the - because we do not have - radii We can also sayOk, since
r does not equal
1, we are not working with a unit circle but we have found
r, which is our radius.
Now that we know the value of r, which is ,
we need to look at the identities of cos, csc and tan.The identities: Now that we know their identities and know the radius of our circle, we can find the exact values of cos, csc and tan. The exact values for cos, csc and tan given the point (4,-7) are:
