Answer:
b. They can both be 90 degree angles
c. Acute angles are by definition 90 degrees, and acute is less than but not equal to 90 degrees
d. should be always
e. should be never (explanation: they have to be adjacent to be supplementary, and vertical angles are never adjacent)
Step-by-step explanation:
The correct answer for the question that is being presented above is this one: "B.a circle with a radius of 4 in." <span>circles have an area of16 pi in2 should have a radius of 4 in.
</span>
The area of a circle is this:
Area = pi * r^2
16 pi = pi * r^2
r^2 = 16
r = 4.
Answer:
f(-6)= -4
Step-by-step explanation:
f(x)=8+2x for f(-6)
-----
x= -6
substitute: 8+2(-6)
simplify using PEMDAS: 8+ (-12)
simplify using PEMDAS: -4
The answer would be -37.5
