Answer:
C. m∠4 = m∠8
D. m∠2 = m∠7
Step-by-step explanation:
Here, we use the principles of alternate angles, corresponding angles and vertically opposite angles to confirm which of the statements are true. Alternate angles are always equal, corresponding angles are equal, likewise vertically opposite angles.
From the given question, it was given that a is parallel to b. Thus, it can be observed and deduced that;
m∠4 = m∠8 (corresponding angles)
and
m∠2 = m∠3 (vertically opposite angles)
m∠3 = m∠7 (corresponding angles)
So that,
m∠2 = m∠7
Thus in the question, statements C and D are true.
Answer:
The answer to your question is x = 35°
Step-by-step explanation:
Data
angle x = ?
Opposite side = 7
Adjacent side = 10
Process
To answer this question use trigonometric functions. The trigonometric function that relates the Opposite side and the adjacent side is the tangent.
Tan x = Opposite side / Adjacent side
- Substitution
Tan x = 7 / 10
- Simplification
Tan x = 0.7
- Result
Tan⁻¹ x = x = 34.99 or x ≈ 35°
