Answer:
m∠ABC = 130°
Step-by-step explanation:
BD is the angle bisector of angle ABC .
Therefore, ∠ABD ≅ ∠DBC
Measure of angle DBC = 65°
Therefore, m∠ABD = m∠DBC = 65°
m∠ABC = m∠ABD + m∠DBC
= 65° + 65°
= 130°
Answer:
6, 3
Step-by-step explanation:
Answer:
B, (6,0)
Take the average of the x values and the average of the y values:
(3+9)/2 = 6
(-2+2)/2 = 0
This means the answer (the average (midpoint) of the two points) is (6,0)
Answer:
CA ≈ 3.1 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan40° =
=
=
( multiply both sides by CA )
CA × tan40° = 2.6 ( divide both sides by tan40° )
CA =
≈ 3.1 ft ( to the nearest tenth )
