Answer:
∠x = 72°
Step-by-step explanation:
since two sides are equal, their opposite angles are equal.
Then the upper angle is also equal to 54°.
All triangle angles add up to 180°.
∠x = 180 - 54 - 54 = 72°
Hello,
x/4=14/16
==>x/4=7/8
==>x=7*4/8
==>x=7/2
==>x=3.5
What else?
Answer: C
Step-by-step explanation:
Answer C
3 10 =30 2 10 + 10=30 so i think its ten they both equal 30
Let's say that f(x) = ax^2 + bx + c
if f(g(x)) = 9x^2 + 6x + 7:
a(3x + 1)^2 + b(3x + 1) + c = 9x^2 + 6x + 7
9ax^2 + 6ax + a + 3bx + b + c = 9x^2 + 6x + 7
Comparing the two equations, we can see that a = 1, b = 0 and c = 6, therefor f(x) = x^2 + 6
