Answer:
D. x=4
Step-by-step explanation:
We can solve this with the Pythagorean Theorem for the right triangle that we can see (which is half of the triangle).
The bottom length is 3 and the hypotenuse is 5.
The Pythagorean Theorem is a²+b²=c².
We can plug this in:
3²+x²=5²
9+x²=25
x²=16
x=4
Answer:
40 degrees
Step-by-step explanation:
x and 40 (degrees) are "vertical angles" and are thus equal. So x = 40 degrees.
Since you don't have b and c as a answer choice cause those are the answer
