Answer:
hello there mate
Step-by-step explanation:
To find the measure of the third angle you should keep in mind the following:
The sum of the three interior angles of a triangle is 180 °.
We have then
k + 27 + 10 = 180
Clearing k:
k = 180-27-10 = 143
K = 143 °
Answer:
the value of k is 143 °
If it looks like this:
A -------------------- B
| |

| |
C -------------------- D
Then BC is the hypotenuse of a right triangle with sides 16 and 30. Using the Pythagorean Theorem you can solve for the length of the hypotenuse:


We have the expression . To write a equivalent expression, we are going to rewrite the denominator of our expression using its common denominator 4:
Now, notice that we are basically diving 1 by , so we have a division involving fractions, and remember that to divide fractions, we just need to invert the second fraction and multiply:
We can conclude that the equivalent expression of is .

Answer:
64
Step-by-step explanation:
x-13+2x+1=180
3x-13+1=180
3x-12=180
3x=180+12
3x=192
x=192/3
x=64
