Answer:
97 degrees
Step-by-step explanation:
Angle d and the angle to the right of angle c are alternate interior angles. This means that these angles are congruent. The angle next to angle c is equal to 180-83 degrees, which is the same as 97 degrees. So, angle d has a value equivalent to 97 degrees.

Answer:
12 = -3 - 3x
Step-by-step explanation:
Same concept as the last question I answered. First, let's derive a formula from the given model. So we have 3 negative x and 3 negative 1 which equal to 12 positive ones, this can be written as:
-3x - 3 = 12
which can be rewritten as
12 = -3 - 3x
A counterexample for the expression secФ / tanФ = sinФ is 45°
This is a FALSE statement.
Explanation:
Solving Right-hand side:
SecФ = 1 / CosФ
tanФ = SinФ / CosФ
secФ/tanФ = 1 / CosФ ÷ SinФ / CosФ
secФ/tanФ = 1 / CosФ × CosФ/SinФ
secФ/tanФ = CosФ / SinФCosФ
secФ/tanФ = 1 / SinФ
Hence,
Left-hand side ≠ Right-hand side
