Answer:
m < amc = 54°
Step-by-step explanation:
< amb and < bmc are complementary angles whose sum equals 90°.
Therefore, to find the value of 2x°, we must first solve for x.
We can establish the following equality statement:
< amb + < bmc = < amc
< 2x° + (x + 9)° = 90°
Combine like terms:
2x° + x° + 9° = 90°
3x° + 9° = 90°
Subtract 9 from both sides:
3x° + 9° - 9° = 90° - 9°
3x = 81°
Divide both sides by 3 to solve for x:
3x/3 = 81°/3
x = 27°.
Since x = 27°, substitute its value into 2x° to find m < amc:
2x° = 2(27°) = 54°
Therefore, m < amc = 54°

Answer:
a and f
Step-by-step explanation:
1500 is double 750, which is the combined calories of lunch and breakfast, which is only 1 third.
The equation is y = 1/2 x + 13, where x is the number of days, and y is the length of the barrier
Plug in 12 for y and rewrite the equation.
12 = 4x + 4
Subtract 4 from both sides.
8 = 4x
Divide by 4 on both sides.
2 = x
The ordered pair is (2, 12) and x = 2.
easy way...
multiply Base x height (for both)
30 inches x 12 inches = 360 in
16 in. x 12 in = 192 in.
then add both
360 + 192 = 552
A=552 in²
