A triangle will have a total of 180 degrees.
Since it is a right triangle, we know that one angle is 90 degrees. We also know that one of the other angles is 51.
90 + 51 + x = 180
141 + x = 180
Subtract 141 on both sides.
x = 180 - 41
x = 39
The value of b is 39 degrees.
Answer:
C a dilation will always produce similar figures
Step-by-step explanation:
If the scale factor is >1 then the figure will get larger
< 1 the figure gets smaller
=1 it is congruent
We can rotate the figure but that is not by dilation. dilation does not change the orientation, unless the scale factor is negative( which is a reflection)
Answer:
D
Step-by-step explanation:
Answer:
The answer is 6.451 or 6.5 rounded
Step-by-step explanation:
The way to solve this is to find all the degrees inside the triangle first
you have two given degrees which are 21 and 90 degrees
add those numbers up and subtract it from 180. That is the last corner degree
you then use that information to find all the side lengths using the given hypotenuse length.
Btw its geometry not really trig.
