Answer:
axis of symmetry: x = 4
Step-by-step explanation:
Vertex ( 4 , 3) x = 4
Answer:
y = 40
Step-by-step explanation:
So, the direct variation equation is y = x.
Substitute 32 for x and find y.
So, y = 40 when x = 32.
Answer:
Step-by-step explanation:
None. there are always 2 acute angles in a 90 degree triangle
You have to find the cos of angle A, so use the Pythagorean equation and trig laws to find the other side of the triangle created by angle A. 3^2 + x^2 = 5^2. x=4. This means cos(A) = 4/5). Make both cos (A) and cos (B) have equal denominators, and add. 148/185 + 60/185 = 208/185. This answer is correct, though it doesn’t appear to be any of the answers you wrote, so either those answers are wrong or you wrote something incorrectly in the problem.
