Answer:
x
Step-by-step explanation:
x=\sqrt{19^2-10^2}=\sqrt{361-100} =\sqrt{261} \approx16.15549\\\approx16.16
Answer:
11
Step-by-step explanation:
h - f = 7 - (-4) = 7 + 4 = 11
Answer:
128°
Step-by-step explanation:

It will b answer A. Because they all have equal parts
If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.
Value of X is 9 and Angle 6 is 79°
If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.
If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.
If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent.
Since, angle 1 and angle 4 are vertically opposite angles . Hence, these are equal.
∠1 = ∠4 = 11x + 2
Similarly, ∠6 and ∠7 are vertically opposite angles.
Thus, ∠6 = ∠7 = 8x + 7
If two parallel lines are cut by a transversal, then the sum of interior angles on one side is equal to 180 degree.
Therefore, ∠4 + ∠6 = 180
11x + 2 + 8x + 7 = 180
19x + 9 = 180
19x = 171
x = 9
Value of angle 6 = value of angle 7
= 8x + 7
= 8 (9) + 7
= 79 Degree
