Answer:
4. x=120
5. x=65
9. x=150
10. x=45
Step-by-step explanation:
4. Half=180
There is already a 60, so you do 180-60=120. x=120.
5. This is a parallel line, so you determine the opposite angle of 115, which is 65. That just becomes the x. x=65
9. It is similar to #5, You look at the opposite side of 30 (15+15) which is 150. That just comes to the other side which is x=150.
10. A triangle has 180 degrees in total. 45 degrees is already given, and line j is 90 degrees which means a full line is 180. 180-90=90.
90+45=135
180-135=45
x=45
Hope this helped!

Answer:
C. 24
Step-by-step explanation:
a^2 + b^2 = c^2
a and b are the legs of the right triangle. c is the hypotenuse.
a^2 + 10^2 = 26^2
a^2 + 100 = 676
a^2 = 576
Since "a" is to the 2nd power, the opposite would be to square root it.
Square root of 576 is 24.
x = 24
