The angle bisector of ∠ACD in rhombus ABCD makes a 64° angle with the diagonal
1 answer:
Answer:
104°
Step-by-step explanation:
Even a crude diagram can be helpful. Half of angle ACD is the complement of the 64° angle made with diagonal BD. Since that complement, 26°, is half the bisected angle, which is half the measure of ∠BAD, the measure of ∠BAD must be 4×26° = 104°.
___
Opposite angles of a rhombus are congruent, and each diagonal is a bisector of the angles at its endpoints. The diagonals bisect each other and meet at right angles.

Hi there!
f(x) = -2x - 3
Plug in 0 for "x" to solve for f(0):
f(0) = -2(0) - 3
f(0) = -3
Since the question is asking you to evaluate f(0) - 7, simply subtract:
-3 - 7 = -10.
