Answer:
x = 30
Step-by-step explanation:
because the interior angles of a triangle = 180° so if you subtract 90° you get 90. in order to get 90 you can use the equation x + 2x = 90 which you will then get x = 30
Answer:
9x/-1 is the correct answer
Step-by-step explanation:
Answer:
Answer is 65 =, option C
Step-by-step explanation:
angle xoz = 86
This means that 3x + 6x+ 23 = 86.
Because angle xoy and angle yoz = angle xoz
Solving for x yields 7.
Substituting it in the formula for yoz which is 6x + 23 gives off 65.
